Of particular interest are those compounds in which X is 0, especially when Z is optionally substituted heteroaryl, S, S021 NH, NCH31 NCOCH3, CH(C6H5), CH(OH), CH=CH, OCH21 CH20t CH(CH3)0, S(O)CH21 SM2CH21 S0201 CO.CH 0 or CO CH and more Darticularly, 0, CH 0, OCH C. 4 16 01 16 z S020 or CH(OH). The compounds of the invention contain at least one carbon-carbon double bond, and are sometimes obtained in the form of mixtures of geometric isomers. However, these mixtures can be separated into individual isomers, and this invention embraces such isomers, and mixtures thereof in all proportions including those which consist substantially of the (Z)-isomer and those which consist substantially of the (E)-isomer.
The individual isomers which result from the unsymmetrically substituted double bond of the propenoate group are identified by the commonly used terms "E" and "Z". These terms are defined according to the CahnIngold-Prelog system which is fully described in the literature (see, for example, J March, "Advanced Organic Chemistry", 3rd edition, Wiley-Interscience, page 109 et seq).
1 1 i 1 t i I i Usually one isomer is more active fungicidally than the other, the more active isomer usually being the one wherein the groups -C02CH3 and -OCH3 are on opposite sides of the olefinic bond of the propenoate group (the (E)- isomer). These (E)-isomers form a preferred embodiment of the invention.
The substituent Z in compound (I) is optionally substituted aryl or optionally substituted heteroaryl. Where valency allows, each of the optionally substituted groups aryl or heteroaryl can carry up to 5 substitutents. The term "aryl" includes phenyl in particular, and naphthyl. The term "heteroaryl" includes 5- and 6membered heterocyclic groups containing one or more of each of the heteroatoms 0, S and N (preferably S or N), fused benzenoid and heteroaromatic ring systems, and, in each case, the corresponding N- oxides. Examples of heteroaryl groups which Z may be are pyridinyl, pyrimidinyl, pyrazinyl, pyridazinyl, 1,2,3-, 1,2,4-, and 1,3,5-triazinyl, 1,2,4,5-tetrazinyl, 1,2,3- and 1,2,4triazolyl, thienyl, furyl, pyrrolyl, thiazolyl, oxadiazolyl, quinolinyl, isoquinolinyl, quinoxalinyl, benzothienyl, benzoxazolyl and benzthiazolyl and, where appropriate, the corresponding N-oxides.

p i 1 - 74 The compounds of the invention of formula (I) can be made by a variety of methods, and some of these are illustrated in Schemes I to VIII. Throughout these Schemes, the terms Z, X, A, B, E, K, Rit R2, R3, R4 and R5 are as defined above, R6 is hydrogen or a metal (such as sodium or potassium), R is an alkyl group, and L is a leaving group such as a halide (chloride, bromide or iodide), a CH3S04-anion, or a sulphonyloxyanion. Each of the transformations described in Schemes I to VIII is performed at a suitable temperature and either in a suitable solvent or in the absence of a solvent.
Scheme I illustrates ways in which the methyl betamethoxypropenoate group can be constructed in the final stages of the preparation of the compounds of the invention from precursors with a preformed framework of 3 aromatic rings. Alternatively, the methyl beta-methoxypropenoate group may be constructed at an earlier stage of the preparation, in which case the final step or steps comprise elaboration of other parts of the compounds of the invention to form the framework of 3 aromatic rings. Examples of procedures of this kind are shown in Schemes III to VIII.
In whichever order the steps are carried out to prepare the compounds of the invention, the diphenyl ether or thioether linkage which is common to all the compounds of the invention can be prepared by one of the coupling reactions shown in Scheme II. For a review of the Ullmann ether synthesis see A.A. Moroz and M.S. Shrartsberg, Russian Chem.Reviews, 1974, 43, 679. See also D. Hands, H. Marley, S.J. Skittrall, S.H.B. Wright and T. R. Verhoeven, J. Reterocyclic Chem., 1986, 23, 1333. These couplings are often performed in the presence of a catalyst which consists of a transition metal or a salt or compound of a transition metal, such as copper or a coppgr salt or compound, or a mixture thereof. In Scheme II, the 4 1 1 i 1 1 term W represents either the group Z-X-, wherein Z and X are as defined above, or a group which can be converted by standard procedures described in the chemical literature into the group Z-X-; for example W can be -OH, -SH, or - NHR4. The term Y represents either the alpha-linked methyl beta-methoxypropenoate group of the compounds of the invention or a group which can be converted into such a group by standard methods described in the chemical literature and/or described in Scheme I an the following d paragraphs. For example Y can be -CH2COOH, -CH2COOMe or -CHO. In the context of Scheme II, the term L is preferably a halogen. Thus compounds of formula (M) react with compounds of formula (XII) under the conditions of the Ullmann reaction already described to give the is intermediates of formula (VIII). As an example of one of the coupling reactions shown in Scheme II, substituted 3 phenoxyphenols, as their salts, undergo coupling with 2 bromo- or 2-chlorophenylacetic acid salts to give, after acidification, substituted 2-(3-phenoxyphenoxy)phenyl acetic acids (compare, for example, GB 2078-743, Ihara Chem.Ind., 27.06.80). Alternatively, intermediates of formula (VIII) can be made by reacting compounds of formula (IX) with compounds of formula (X) under the conditions of the Ullmann reaction already described.
In one particular aspect, the invention includes a process for the preparation of the compound of formula (I) which comprises reacting a compound of general formula (XIIa) Y1 E CH302C CH.OCH3 wherein Y is halogen with a phenol or thiophenol of general formula (XIa):
(XI I a) A B n,_i (XI a) in the presence of a base, or with a salt of the phenol or thiophenol (XIa), preferably in the -presence of a catalyst which comprises a suitable transition -.etal, a transition metal salt or compound or a mixture thereof.
The compounds of the invention of formula (I) can be prepared from the phenylacetates of formula (III) or the ketoesters of formula (VI) by the steps shown in Scheme I.
Thus compounds of formula (I) can be prepared by treatment of phenylacetates of formula (III) with a base (such as sodium hydride or sodium methoxide) and methyl formate. If a species of formula CH3L, wherein L is as defined above, is then added to the reaction mixture, compounds of formula (I) may be obtained. If a protic acid is added to the reaction mixture, compounds of formula (II) wherein R6 is hydrogen are obtained. Alternatively, the species of formula (II) wherein R6 is a metal (such as sodium) may themselves be isolated from the reaction mixture.
Compounds of formula (II) wherein R6 is a metal can be converted into compounds of formula (I) by treatment with a species of formula CH3L, wherein L is as defined above. Compounds of formula (II) wherein R6 is hydrogen can be converted into compounds of formula (I) by successive treatments with a base (such as potassium carbonate) and a species of general formula CH3L.
Alternatively, compounds of formula (I) can be prepared from acetals of formula (IV) by elimination of methanol under either acidic or basic conditions. Examples of reagents or reagent mixtures which can be used for this transformation are lithium di-isopropylamide; potassium hydrogen sulphate (see, for example, T Yamada, H Hagiwara and H Uda, J.Chem.Soc., Chemical Communications# 1 77 1980, 838, and references therein); and triethylamine, often in the presence of a Lewis acid such as titanium tetrachloride (see, for example, K Nsunda and L Heresi, J.Chem.Soc., Chemical Communications, 1985, 1000).
Acetals of formula (IV) can---be prepared by treatment of methyl silyl ketene acetals of formula (V), wherein R is an alkyl group, with trimethyl orthoformate in the presence of a Lewis acid such as titanium tetrachloride (see, for example, K Saigo, M Osaki and T Mukaiyama, Chemistry Letters, 1976, 769).
Methyl silyl ketene acetals of formula (V) can be prepared from phenylacetates of formula (III) by treatment with a base and a trialkylsilyl halide of formula R3Sici or R3SiBr, such as trimethylsilyl chloride, or a base (such as triethylamine) and a trialkylsilyl triflate of formula R3si-OSO2CF3 (see, for example, C Ainsworth, F Chen and Y Kuo, J.Organometallic Chemistry, 1972, 46, 59).
It is not always necessary to isolate the intermediates (IV) and (V); under appropriate conditions, compounds of formula (I) may be prepared from phenylacetates of formula (III) in "one pot" by the successive addition of suitable reagents listed above.
Alternatively, compounds of formula (I) can be prepared by treatment of ketoesters of formula (VI) with a methoxymethylenating reagent, for example, methoxymethylenetriphenylphosphorane (see, for example, W Steglich, G Schramm, T Anke and F Oberwinkler, EP 0044448, 4.7.1980).
Ketoesters of formula (VI) may be prepared by methods described in the literature. Particularly useful methods include (i) the reaction of appropriate phenylmagnesium halides or phenyl-lithium species with dimethyl oxalate using the method described by L M Weinstock, R B Currie and A V Lovell, Synth.Commun., 1981, 11, 943 and references therein; (ii) oxidation of phenylacetates of - 78 formula (III) using selenium dioxidet generally in the absence of a solvent, and generally at a temperature above 100'C; and (iii) oxidation of mandelic acid esters using, for example, manganese oxide in a suitable solvent.
Phenylacetates of formula (III) and the corresponding phenylacetic acids of formula (VII) may also be prepared by numerous other methods described in the chemical literature. For example, several useful methods are described by D C Atkinson, K E Godfrey, B Meek, J F Saville and M R Stillings, J.Med.Chem., 1983, 26, 1353 and D C Atkinson, K E Godfrey, P L Meyers, N C Phillips, M R Stillings and A P Welbourn, I.Med.Chem., 1983, 26, 1361. Furthermore, many of the methods described for the preparation of 2-arylpropionic esters and acids by J-P Rieu, A Boucherle, H Cousse and G Mouzin, Tetrahedron, 1986, 42, 4095, are also applicable to the preparation of phenylacetates of formula (III) and phenylacetic acids of formula (VII) using appropriate precursors wherein the ortho substituted-phenoxy substituent and the substituent E are already present.

Thus, in scheme III, in the-presence of a base, and sometimes in the presence of a transition metal or transition metal salt catalyst, such as a copper or copper salt catalyst, compounds of formula (XIII) react with aromatic or heteroaromatic compounds of formula ZL, wherein Z and L are as defined above, or with iodonium salts of formula Z21 +T-, wherein Z is as defined as above and T- is a counter ion, such as a halide ion, or with aryl or heteroarylbismuth species, to give compounds of formula (XIV). In addition, in the presence of a base, is compounds of formula (XIII) react with aryl- or heteroarylsulphonyl halides of formula W02Q1 wherein Z is as defined above and Q is a halogen, to give compounds of formula (XV). Furthermore, and also in the presence of a base, compounds of formula (XIII) react with arylalkyl or heteroarylalkyl species of formula ZCHR1L, wherein Z, Ri and L are as defined above, to give compounds of formula (XVI).
In scheme IV, the thiols of formula (XVII), generally in the presence of a base, react with aromatic or heteroaromatic compounds of formula ZL, or with iodonium. salts of formula Z21 +T-, or with aryl- or heteroarylbismuth species, to give compounds of formula (XVIII) in ways which are analogous to the reactions of the corresponding phenols of formula (XIII) shown in Scheme III. Similarly, and again in the presence of a base, the thiols of formula (XVII) react with arylalkyl or heteroarylalkyl species of formula ZCHR1L to give compounds of formula (XIX). The sulphides of formula (XVIII) and (XIX) can be oxidised to the corresponding sulphoxides and sulphones by standard methods described in the chemical literature.
82 - In Scheme V, compounds of formula (XX) react with hydroxy-derivatives of aromatic or heteroaromatic compounds of formula ZOH, wherein Z is as defined above, often in the presence of a base, to form compounds of formula (XXI). Furthermore, compounds of formula (XX) react with trialkylphosphites of formula P(OR)3 or with species of formula M+P(0)(OR)2, wherein R is as defined above in each case and M is a metal such as sodium or lithium, to give phosphonates of formula (XXII).
Phosphonates of formula (XXII), in the presence of a base, react with aldehydes or ketones of formula ZR1C:O, wherein Z and Ri are as defined above, to give olefins of formula (XXIV). In addition, aldehydes or ketones of formula (XXIII), on treatment with phosphonate anions of formula ZR1C-P(O)(OR)2M+. wherein Z, R, Ri and M are as defined above, or with the corresponding phosphoranes, also give olefins of formula (XXIV). The olefins of formula (XXIV) can be reduced to the compounds of formula (XXV) by, for example, hydrogenation over an appropriate catalyst.
In Scheme VI, compounds of formula (XXVI), in the presence of a base, react with acid halides of formula ZCOQ, wherein Z and Q are as defined above, or, in the presence of an appropriate dehydrating agent, react with acids of formula W02H, wherein Z is as defined above, to give compounds of formula (XXVII).
Intermediates of formula (XXVI) can also be converted into other types of compound of the invention of formula (I) by methods described in the chemical literature. For example, compounds of formula (XXVI) wherein R 4 is hydrogen can be converted, via diazotisation, into the corresponding sulphonyl chlorides (compare organic Syntheses, 1981, 60, 121) and then, by treatment with alcohols or phenols in the presence of a base, into sulphonic esters.
1 Compounds of the invention of formula (I) wherein at least one of A and B is hydrogen may be converted into compounds of the invention of formula (I) wherein at least one of A and B are certain substituents (such as a halogen or a nitro or acyl group) by electrophilic substitution processes of the kind described in the chemical literature.
The intermediates of formulae (XIII), (XVII), (XX), (XXIII) and (XXVI) can be prepared by processes described in the chemical literature and by processes of the kinds described in Schemes I and II.

The aldehydes or ketones of formula (XXIII) can react with oxyamines of formula ZONH2 or ZCHR1ONH2, or with hydrazines of formula MR1NH21 wherein Z and Ri are as defined above, to give compounds of the invention of formula (I) where X is the group ON--CR2, CHR1ON=CR2, or NR1N=CR2 respectively. Also, compounds of formula (XXIII) can react with Grignard reagents of formula ZMgHal or ZCR1R2MgHal, where Hal is chlorine, bromine or iodine and Z, Ri and R2 are as defined above, to give compounds of the invention of formula (I) where X is CR2(0H) or CR1R2CR2(0H) respectively. Also, compounds of formula (XXIII) can react with amines of formula ZNHR1 or ZCR1R2NHR1, wherein Z, Rl and R2 are as defined above, in the presence of a reducing agent (such as sodium - 88 cyanoborohydride or hydrogen gas in the presence of suitable metal catalyst) to give compounds of the invention of formula (1) where X is NR1CHR2 or CR1R2NR1CHR2. When the reducing agent is left is out and when R' is H, then the immediately preceding procedure will give compounds of the invention of formula (I) where X is N=CR2 or CR1R2N=CR2.
Compounds of formula (XXVIII) where R2 is H, can also be oxidised to carboxylic acids of formula (XXIX), using for example Jones' reagent (chromium trioxide in sulphuric acid). The carboxylic acids (XXIX) can be converted directly into compounds of the invention of formula (I) where, for example, X is 02C, CHR10CO, SCO, CHR1SCO, NR4C0 or CHR1NR4CO, using one of the standard coupling reagents well known in the literature, such as dicyclohexylcarbodiimide or carbonyldiimidazole, in a suitable solvent.
Alternatively, the carboxylic acids of formula (XXIX) can be converted into the acid chlorides of formula (XXX) by treatment with, for example, thionyl chloride or oxalyl chloride. The acid chlorides of formula (XXX) can then react, for example, with compounds of formula ZOH, ZCHR10H, ZSH, ZCHR1SH, WR4H or ZCHR1NR4H in a suitable solvent, in the presence of a base, to give compounds of the invention of formula (I) where X is 02C, CHR10CO, SCO, CHR1SCO, NR4CO, or CHR1NR4C0 respectively.
Compounds of formula (XXVIII) can also react directly with compounds of formula ZL, optionally in the presence of a base, where Z is a reactive aromatic group (for example nitrophenyl) or heteroaromatic group (for example 2-pyridyl or 2-pyrimidinyl) to give compounds of the invention of formula (XXI). It may be necessary first to generate the oxygen anion of compounds of formula (XXVIII) with a strong base such as sodium hydride.
Additionally, compounds of formula (XXVIII) can be converted into compounds of formula (XX) by treatment, for 1 j - 89 example, with a halogenation agent such as thionyl chloride or phosphorus tribromide, where L is chlorine or bromine, or by treatment with a sulphonyl halide (such as p-toluenesulphonyl chloride) in the presence of an acid acceptor, where L is a sulphonyloxy group. Compounds of formula (XX) can then be used as shown in Scheme V. Additionally, where L is halogen, they can be converted by reaction with a phosphine of formula Z(R5)2P, wherein R5 is as defined above, into compounds of the invention of formula (1), where X is the group (R5)2P+CHR2Q-. These compounds can then react successively with a base and a carbonyl compound of formula WOR1, wherein Z and Ri are as defined above, to give olefins of formula (XXIV).
Scheme VIII illustrates examples of intermediates of formula (VIII), shown in Scheme II, where W is any group that can be converted to ZX-, and Y is any group that can be converted to the methyl beta-methoxypropenoate group.
Compounds of formula (XXXI) can react with compounds of formula (XXXII) to give compounds of formula (XXY.III), using the general Ullmann coupling conditions described in detail for the reaction of compounds of formula (Xl) and (XII) in Scheme II. The acids of formula (XXXIII) can be converted into methyl esters of formula (XXXIV) by reaction with methanol in the presence of acid (for example hydrochloric acid). Compounds of formula (XXXIV) can then be converted into methyl beta-methoxypropenoates of formula (XXVIII) by the methods described in detail in Scheme I.
Alternatively, the intermediates of formula (XXXIV) can be converted into intermediates of formulae (XXXVIII), (XXXV), (XXXVI), (XxXVII) and (III) using the methods described in Scheme VII for the conversion of the propenoates of formula (XXVIII) into compounds of formula (XXIII), (XX), (XXIX)o (XXX) and (I). Compounds of formula (III) can be converted into compounds of formula (I) as shown in Scheme I.

It also provides intermediate chemicals of formulae (II)-(VII), (XIII)-(XXX), and (XXXIII)-(XXXVIII).
The compounds are active fungicides and may be used to control one or more of the following pathogens:
Pyricularia oryzae on rice. Puccinia recondita, Puccinia striiformis and other rusts on wheat, Puccinia hordei, Puccinia striiformis and other rusts on barley, and rusts on other hosts, e.g. coffee, pears, apples, peanuts, vegetables and ornamental plants. Erysiphe graminis (powdery mildew) on barley and wheat and other powdery mildews on various hosts such as Sphaerotheca macularis on hops, Sphaerotheca fuliginea on cucurbits (e.g. cucumber), Podosphaera leucotricha on apple and Uncinula necator on vines. Helminthosporium spp., Rhynchosporiu spp., Septoria spp. , Pseudocercosporella herepotrichoides and Gaeumannomyces graminis on cereals. Cercospora arachidicola and Cercosporidium personata on peanuts and other Cercospora species on other hosts, for example, sugar beet, bananas, soya beans and rice.

Thanatephorus cucumeris on rice and other Rhizoctonia species on various host such as wheat and barley, vegetables, cotton and turf.
Some of the compounds show a broad range of activities against fungi in vitro. They may also have activity against various post-harvest diseases of fruit (e.g. Penicillium digitatum. and italicum and Trichoderma viride on oranges, Gloeosporium musarum on bananas and Botrytis cinerea on grapes).
Further, some of the compounds may be active as seed dressings against Fusarium spp., Septoria spp., Tilletia spp., (bunt, a seed borne disease of wheat), Ustilago spp., Helminthosporium spp. on cereals, Rhizoctonia solani on cotton and Pyricularia oryzae on rice.
The compounds may have systemic movement in plants. Moreover, the compounds may be volatile enough to be active in the vapour phase against fungi on the plant.
Many of the compounds of formula (1), including those in which X is 0, are safer on certain crops (e.g. vines) than known structurally related compounds.
The invention therefore provides a method of combating fungi, which comprises applying to a plant, to seed of a plant, or to the locus of the plant or seed, an effective amount of a compound as hereinbefore defined, or a composition containing the same.
The compounds may also be useful as industrial (as opposed to agricultural) fungicides, e.g. in the prevention of fungal attack on wood, hides, leather and especially paint films.
The compounds may be used directly for fungicidal purposes but are more conveniently formulated into compositions using a carrier or diluent. The invention thus provides a fungicidal composition comprising a 94 compound of general formula (I) as hereinbefore defined, and a fungicidally acceptable carrier or diluent.
Used as fungicides, the compounds can be applied in a number of ways. For example they can be applied, formulated or unformulated, directly to the foliage of a plant, to seeds or to other medium in which plants are growing or are to be planted, or they can be sprayed on, dusted on or applied as a cream or paste formulation, or they can be applied as a vapour or as slow release granules. Application can be to any part of the plant including the foliage, stems, branches or roots, or to soil surrounding the roots, or to the seed before it is planted; or to the soil generally, to paddy water or to hydroponic culture systems. The inventioncompounds may is also be injected into plants or sprayed onto vegetation using electrodynamic spraying techniques or other low volume methods.
The term "plant" as used herein includes seedlings, bushes and trees. Furthermore, the fungicidal method of the invention includes preventative, protectant, prophylactic and eradicant treatment.
The compounds are preferably used for agricultural and horticultural purposes in the form of a composition. the type of composition used in any instance will depend upon the particular purpose envisaged.
The compositions may be in the form of dustable powders or granules comprising the active ingredient (invention compound) and a solid diluent or carrier, for example fillers such as kaolin, bentonite, kiesselguhr, dolomite, calcium carbonate, talc, powdered magnesia, Fuller's earth, gypsum, diatomaceous earth and China clay. Such granules can be performed granules suitable for application to the soil without further treatment. These 1 1 i i 0 J i granules can be made either by impregnating pellets of filler with the active ingredient or by pelleting a mixture of the active ingredent and powdered filler. Compositions for dressing seed may include an agent (for example a mineral oil) for assisting the adhesion of the composition to the seed; alternatively the active ingredient can be formulated for seed dressing purposes using an organic solvent (for example N- methylpyrrolidone, propylene glycol or dimethylformamide). The compositions 10 may also be in the form of wettable powders of water dispersible granules comprising wetting or dispersing agents to facilitate the dispersion in liquids. The powders and granules may also contain fillers and suspending agents.
Emulsifiable concentrates or emulsions may be prepared by dissolving the active ingredient in an organic solvent optionally controlling a wetting or emulsifying agent and then adding the mixture to water which may also contain a wetting or emulsifying agent. Suitable organic 20 solvents are aromatic solvents such as alkylbenzenes and alkylnaphthalenes, ketones such as isophorone, cyclohexanone, and methylcyclohexanone, chlorinated hydrocarbons such as chlorobenzene and trichlorethane, and alcohols such as benzyl alcohol, furfuryl alcohol, butanol and glycol ethers.
Suspension concentrates of largely insoluble solids may be prepared by ball or bead milling with a dispersing agent and including a suspending agent to stop the solid settling.
Compositions to be used as sprays may be in the form of aerosols wherein the formulation is held in a container under pressure in the presence of a propellant, e.g. fluorotrichloromethane or dichlorodifluoromethane.
The invention compounds can be mixed in the dry state with a pyrotechnic mixture to form a composition suitable for generating in enclosed spaces a smoke containing the compounds.
Alternatively, the compounds may be used in microencapsulated form. They may also be formulated in biodegradable polymeric formulations to obtain a slow, controlled release of the active substance.
By including suitable additives, for example additives for improving the distribution, adhesive power and resistance to rain on treated surfaces, the different compositions can be better adapted for various utilities.
The invention compounds can be used as mixtures with fertilisers (e.g. nitrogen-, potassium-, or phosphorus- containing fertilisers). Compositions comprising only granules of fertiliser incorporating, for example coated with, the compound are preferred. Such granules suitably contain up to 25% by weight of the compound. The invention therefore also provides a fertiliser composition comprising a fertiliser and the compound of general formula (I) or a salt or metal complex thereof.
Wettable powders, emulsifiable concentrates and suspension concentrates will normally contain surfactants e.g. wetting agent, dispersing agent, emulsifying agent or suspending agent. These agents can be cationic, anionic or non-ionic agents.
Suitable cationic agents are quaternary ammonium compounds, for example, cetyltrimethylammonium. bromide. Suitable anionic agents are soaps# salts of aliphatic monoesters of sulphuric acid (for example sodium lauryl sulphate), and salts of sulphonated aromatic compounds (for example sodium dodecylbenzenesulphonate, sodium, calcium or ammonium lignosulphonate, butylnaphthalene sulphonate, and a mixture of sodium diisopropyl- and triisopropyl-naphthalene sulphonates).
1 7 Suitable nonionic agents are the condensation products of ethylene oxide with fatty alcohols such as oleyl or cetyl alcohol, or with alkyl phenols such as octyl- or nonyl-phenol and octylcresol. Other non-ionic agents are the partial esters derived from long chain fatty acids and hexitol anhydrides, the condensation products of the said partial esters with ethylene oxide, and the lecithins. Suitable suspending agents are hydrophilic colloids (for example polyvinylpyrrolidone and sodium carboxymethylcellulose), and swelling clays such as bentonite or attapulgite.
Compositions for use as aqueous dispersions or emulsions are generally supplied in the form of a concentrate containing a high proportion of the active ingredient, the concentrate being diluted with water before use. These concentrates should preferably be able to withstand storage for prolonged periods and after such storage be capable of dilution with water in order to form aqueous preperations which remain homogeneous for a sufficient time to enable them to be applied by conventional spray equipment. The concentrates may conveniently contain up to 95% suitably 10-85%, for example 25-60%, by weight of the active ingredient. After dilution to form aqueous preparations, suitable preparations may contain varying amounts of the active ingredient depending upon the intended purpose, but an aqueous preparation containing 0.00055 or 0.01% to 10% by weight of active ingredient may be used.
The compositions of this invention may contain other compounds having biological activity, e.g. compounds having similar or complementary fungicidal activity or which plant possess plant growth regulating, herbicidal or insecticidal activity.
A fungicidal compound which may be present in the composition of the invention may be one which is capable of combating ear disease of cereals (e.g. wheat) such as Septoria, Gibberella and Helminthosporium spp., seed and soil-borne diseases and downy and powdery mildews on grapes and powdery mildew and scab on apple, etc. By including another fungicide, the composition can have a broader spectrum of activity than the compound of general formula (I) alone.

During this period, water/ethylene glycol (23 ml) was removed by azeotropic distillation. The mixture was cooled and ether (1 1) was added. The ether solution was washed with saturated sodium bicarbonate solution (200 ml) water (3 x 150 ml) and-saturated brine (1 x 150 ml). After drying and filtration, evaporation of the ether solution gave 2-(2bromophenyl)-1,3- dioxolane (121.96g, 98.6% yield) as an oil.

Potassium hydroxide pellets (35.2g; 0.63 mol) were dissolved in water (50 ml) and 3-methoxyphenol (78g; 0.63 mol) was added together with toluene (250 ml). The mixture was heated to and maintained at reflux temperature until water ceased to distil over (a total of 65 ml of water was collected). The mixture was cooled to SOOC and 2-(2-bromophenyl)-1,3,-dioxolane (120 g; 0. 524 mol), DMF (200 ml) and cuprous chloride (0.2g) were added. The mixture was slowly heated to 150-155C and toluene was distilled off. The mixture was maintained at 150-1550C for 6 hours then cooled to 25C and water (500 ml) was added. The mixture was filtered and the residue was washed with ether (200 ml). The filtrate was extracted with ether (3 x 150 ml). The combined ether extracts were washed with 2N sodium hydroxide solution (2 x 150 ml), water (4 x 150 ml) and saturated brine (1 x 200 ml). After drying and filtration the ether solution - 104 - on evaporation gave 2-E2-(3-methoxyphenoxy)phenyll-1,3dioxolane (124.1g, 87.1% yield) as an oil.

2-12-(3-Methoxyphenoxy)phenyll-1,3-dioxolane (32.7g; 0.12 mol) was stirred in a mixture of water (95 ml) and concentrated hydrochloric acid (5 ml) at ambient temperature for 19 hours. The mixture was extracted with ether (2 x 60 ml) and the combined ether extracts were washed with saturated aqueous sodium bicarbonate solution (30 ml), water (3 x 30 ml) and saturated brine (30 ml).
The resulting solution was dried, filtered and concentrated to give almost pure 2-(3-methoxyphenoxy)benzaldehyde (A) (26. 17g, 95.4% yield) as an oil. This material was used without purification for the following step. However, an analytical sample was prepared by chromatography using a mixture of ether and hexane as eluant to give an amber oil.

Acetyl chloride (20 ml) was added to absolute methanol (200 ml) dropwise over 15 minutes with water bath cooling to maintain the temperature at 20250C. A solution of the sulphoxide (B) (27.67g; 0.083 mol) in methanol (40 ml) was added in one portion and the resulting solution was stirred at ambient temperature for 18 hours. The methanol solution was evaporated to dryness under reduced pressure to leave a brown gum (22.78g) which was dissolved in ether (200 ml). The ether solution was washed with saturated aqueous sodium bicarbonate solution and, after filtering off a small quantity of insoluble material, the ether solution was evaporated to dryness and the residue was chromatographed using a mixture of ether and hexane as eluant to give methyl 2-(3-methoxyphenoxy)phenylacetate (C) (15.62g, 69.3% yield) as a viscous oil.

Boron tribromide (12.89g, 0.051 mol) was dissolved in dichloromethane (50 ml) and cooled to 0-50C. A solution of methyl 2-(3methoxyphenoxy)phenylacetate (7.0g; 0.026 mol) in dichloromethane (80 ml) was added dropwise, with stirring over 1 hour. After stirring at 0-5C for 20 minutes the mixture was added dropwise, with stirring to absolute methanol (100 ml) maintaining the temperature at 0-5C. The resulting solution was poured into water (250 ml) containing sodium bicarbonate (12g), and the resulting mixture was extracted with ether (500 mls). The organic phase was washed with water (3 x 200 ml) and saturated brine (150 ml). After drying and filtration, evaporation of the ether solution gave methyl 106 - 2-(3-hydroxyphenoxy)phenylacetate (D) (6.12g, 92.3% yield) as a brown gum. This material was suitable for use in subsequent steps without further purification. However, chromatography using mixtures of ether and hexane as eluant gave material of higher purity as a viscous golden oil which rapidly darkened on exposure to ai - r.
In addition, methyl 2-(3-hydroxyphenoxy)phenylacetate (D) was prepared as follows: A mixture of 2-chlorophenylacetic acid (309, 0.18 mol), potassium carbonate (48.6g, 0.34 mol), and 3-methoxyphenol (43.5g, 0.35 mol) was heated with stirring at 1400C in the presence of a catalytic amount of copper(I) chloride. After 3 hours, GC and TLC analysis indicated the absence of the starting acid. The reaction mixture was allowed to cool (with the addition of dry DMF (5 ml) at 70C to prevent the mixture from becoming too viscous), poured into water and acidified with concentrated hydrochloric acid. The resulting mixture was extracted with ether and the combined ether extracts were washed with water until neutral. The ether extracts were dried and evaporated to afford a mixture of 3-methoxyphenol (49%) and 2-(3methoxyphenoxy)phenylacetic acid (41%) as a brown mobile oil which was used in the next stage without further purification.
The brown oil was refluxed in methanol (70m1) containing concentrated sulphuric acid (2 ml) for 2P, hours. The reaction mixture was allowed to cool to room temperature and was then poured into water. The resulting mixture was extracted (x 2) with ether and the combined ether extracts were washed with dilute aqueous sodium hydroxide solution, and then with water until neutral and then dried. Evaporation gave crude methyl 2(3methoxyphenoxy)phenylacetate (34.9g) as an orange-brown oil (86% pure by GC). The crude product was combined with another batch (8.2g) which had been prepared by the same method. Repeated short-path distillation (50-120'C at 4x10-2 mbar) then afforded methyl 2-(3-methoxyphenoxy)- c i n - 107 phenylacetate as an oil (37.1g, 95% pure, ca. 60% yield from 2chlorophenylacetic acid). Further amounts of product were obtained in subsequent preparations.
Methyl 2-(3-methoxyphenoxy)phenylacetate (979, 0.36 mol) was heated with concentrated hydrobromic acid (194 ml) in acetic acid (150 ml) at 11CC for 8 hours. After standing at room temperature overnight, more concentrated hydrobromic acid (100 ml) was added and the reaction mixture was reheated to 1100C. After a further 7 hours, all of the starting material had been consumed. The reaction mixture was allowed to cool to room temperature, poured into brine and then extracted with dichloromethane (x 2).The dichloromethane was evaporated to give an oil which was heated at 700C with methanol (400 ml) and concentrated sulphuric acid (2 ml) for 2 hours. The reaction mixture was allowed to cool to room temperature, poured into brine and extracted with dichloromethane (x 2).
The combined extracts were washed with water (until neutral) and then dried, filtered and evaporated to give a brown oil (92.8g). Short-path distillation (150C, 1x10-3 mbar) of a portion (72.8g) afforded methyl 2-(3 hydroxyphenoxy)phenylacetate (D) (41.4g, 57% yield from methyl 2-(3-methoxyphenoxy)phenylacetate) as a golden syrup.

To a suspension of sodium hydride (0.558g, 0.023 moles in DMF (20m1) was added dropwise a solution of methyl 2-(3- hydroxyphenoxy)phenylacetate (D) (2.0g; 0.0077 mol) in DMF (10m1) and methylformate (10g; 0.167 mol) 108 After stirring for 45 minutes, water (100 mls) was added and the mixture was extracted with ether (50 mls). The aqueous layer was acidified with hydrochloric acid to pH 3-4 and the mixture was extracted with ether (2 x 40 mls). The combined ether extracts were washed with water (3 x 30 mls) and saturated brine (1 x 30 ml), and then dried. The ether was evaporated off and the residue was dissolved in DMF (20 ml), and anhydrous potassium carbonate (0.64g; 0.0046 moles) and dimethyl sulphate (0.55g; 0.0044 moles) was added. The mixture was stirred at ambient temperature for 1 hour, then water (100 ml) was added, and the mixture was extracted with ether (2 x 40 ml). The combined ether extracts were washed with water (3 x 20 ml) and saturated brine (20 ml), dried, filtered, is evaporate to dryness, then chromatographed using a mixture of ether and hexane as eluant to give (E)-methyl 2-E2-(3 hydroxyphenoxy)phenyll-3-methoxypropenoate (E) as an amber gum which, on trituration with a mixture of hexane and dichloromethane, gave a white solid, E0.7g, 30% yield from methyl 2-(3-hydroxyphenoxy)phenylacetate (D)] m.p. 115 1160C.
In addition, (E)-methyl 2-C2-(3-hydroxyphenoxy) phenyl]-3-methoxypropenoate (E) was prepared as follows A solution of methyl 2-(3-hydroxyphenoxy)phenylacetate (D) (12g, 0.0465 mol) and methyl formate (55.8g, 0.93 mol) in dry DMF (35 ml) was added dropwise over 45 minutes to a stirredsuspensionof sodium hydride (6.696g of a 50% dispersionin oil, 0.1395 mol, pre-washed with 40-60 petroleum ether) in dry DMF (65 ml). The reaction mixture was stirred at room temperature for 2 hours, poured into water (200 ml), acidified to pH3 with concentrated hydrochloric acid and then extracted with ether (2 x 200m1). The combined organic extracts were washed with brine (2 x 200 ml), dried, filtered and evaporated to give a yellow oil (12.5g, 0.0433 mol).
1 1 - 109 The oil (12.5g, 0.0433mol) was dissolved in dry DMF (100 ml) and potassium carbonate (5.98g, 0.0433 mol) was added.

The compounds were tested against a variety of foliar fungal diseases of plants. The technique employed was as follows.
The plants were grown in John Innes Potting Compost (No. 1 or 2) in 4cm diameter minipots. The test compounds were formulated either by bead milling with aqueous Dispersol T or as a solution in acetone or acetone/ethanol which was diluted to the required concentration immediately before use. For the foliage diseases, the formulations (100 ppm active ingredient except where otherwise indicated) were sprayed onto the foliage and applied to the roots of the plants in the soil. The sprays were applied to maximum retention and the root drenches to a final concentration equivalent to approximately 40 ppm a.i./dry soil. Tween 20, to give a final concentration of 0.05%, was added when the sprays were applied to cereals.
For most of the tests the compound was applied to the soil (roots) and to the foliage (by spraying) one or two days before the plant was inoculated with the disease. An exception was the test on Erysiphe graminis in which the plants were inoculated 24 hours before treatment. Foliar pathogens were applied by spray as spore suspensions onto the leaves of test plants. After inoculation, the plants were put into an appropriate environment toallow infection to proceed and then incubated until the disease was ready for assessment. The period between inoculation and assessment varied from four to fourteen days according to the disease and environment.
The disease control was recorded by the following grading:
4 = no disease 3 = trace -5% of disease on untreated plants i t i 1 i i 1 i 1 I z 1 z j i i - 151 - -1 2 = 6-25% of disease on untreated plants.1 = 26-59% of disease on untreated plants 0 = 60-100% of disease on untreated plants The results are shown in Table VI.
