Throughout Scheme I the terms R 1, R 2, X, Y and Z are as defined above, L is a halogen (iodine, bromine or chlorine) atom or a hydrogen atom, and M is a metal atom (such as a lithium atom) or a metal atom plus as associated halogen atom (such as Mg I, Mg Br or Mg Cl).
Thus compounds of general formula (I) in which R 1 and R 2 are not hydrogen atoms can be prepared by treatment of ketoesters of general formula (II: R 1 is not a hydrogen atom) with phosphoranes of general formula (V: R 2 is not a hydrogen atom) in a convenient solvent such as diethyl ether (see, for example, W Steglich, G Schramm, T Anke and F Oberwinkler, EP 0044448, 4 7 80).
Ketoesters of general formula (II: R 1 is not a hydrogen atom) can be prepared by treatment of metallated species (III) with an oxalate (VI, R 1 is not a hydrogen atom) in a suitable solvent such as diethyl ether or tetrahydrofuran The preferred method often involves slow addition of a solution of the metallated species (III) to a stirred solution of an excess of the oxalate (VI) (see, for example, L M Weinstock, R B Currie and A V Lovell, Synthetic Communications, 1981, 11, 943, and references therein).
The metallated species (III) in which M = Mg I, Mg Br or Mg C 1 (Grignard reagents) can be prepared by standard methods from the corresponding aromatic halides (IV) in which L = I, Br or C 1 respectively With certain substituents X, Y and Z, the metallated species (III) in which M = Li canbe prepared by direct lithiation of compounds (IV) in which L = H using a strong lithium base such as n-butyl-lithium or lithium di-isopropylamide (see, for example, H W Gschwend and H R Rodriguez, Orqanic Reactions, 1979, 26, 1).
Compounds of general formula (IV) can be prepared by standard methods described in the chemical literature.

Compounds of general formula (I) in which R 2 = H can be converted into compounds (I) in which R 2 is not a hydrogen atom by successive treatment with a base (such as potassium carbonate or sodium hydride) and a species of general formula R 2 Q, wherein R 2 and Q are as defined above, in a suitable solvent.
Furthermore, compounds of general formula (I) in which neither RI nor R 2 are hydrogen atoms can be made from acetals of general formula (VIII) in which neither Rl nor R 2 are hydrogen atoms under either basic or acidic conditions, in suitable solvents and at suitable temperatures An example of a suitable base is lithium di-isopropylamide, and potassium hydrogen sulphate is an example of a suitable acidic reagent (see T Yamada, H Hagiwara and H Uda, Journal of the Chem Soc, Chem.
Commun, 1980, 838, and references therein).
Acetals of general formula (VIII) in which neither RI nor R 2 are hydrogen atoms may be prepared from phenylacetic esters of general formula (VII: RI is not a hydrogen atom) by treatment of alkyl silyl ketene acetal derivatives of the species (VII) with trialkylorthoformates in the presence of a Lewis acid in a suitable solvent and at a suitable temperature (see, for example, K Saigo, M Osaki and T Mukaiyama, Chem Letts, 1976, 769).

In addition, compounds of general formula (I) can be made from acrylic acid derivatives of general formula (X) 53 - by successive treatment with bromine, a reagent of general formula R 2 OM, wherein R 2 and M are as defined above, and sodium hydrogen sulphate or a related chemical (see, for example, G Shaw and R N Warrener, Journal of the Chemical Society, 1958, 153, and references therein).

Some of the compounds exhibit herbicidal activity and at the appropriately higher rate of application may be used to combat weeds.
Similarly, some compounds exhibit plant growth regulating activity and may be deployed for this purpose, - again at appropriate rates of application.
This invention, therefore, includes the foregoing uses of the compounds (and compositions containing them) in addition to their principal use as fungicides.
The compounds may be used as such for fungicidal purposes but are more conveniently formulated into compositions for such usage The invention thus provides a fungicidal composition comprising a compound of general formula (I) as hereinbefore defined, or a metal complex thereof; and, optionally, a carrier or diluent.
The invention also 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, a compound or metal complex thereof, as hereinbefore defined.
The compounds and metal complexes of the invention can be applied in a number of ways For example they can be applied, formulated or unformulated, directly to the foliage of a plant, or they can be applied also to bushes and trees, to seeds or to other medium in which plants, bushes or trees 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, bush or tree, for example to 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 hyroponic culture systems The invention compounds may also be injected into plants or trees and they may also be 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.
56 - 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 dusting powders or granules comprising the active ingredient and a solid diluent or carrier, for example fillers such as kaolin, bentonite, kieselguhr, dolomite, calcium carbonate, talc, powdered magnesia, Fuller's earth, gypsum, Hewitt's earth, diatomaceous earth and China clay Such granules can be preformed granules suitable for application to the soil without further treatment These granules can be made either by impregnating pellets of filler with the active ingredient or by pelleting a mixture of the active ingredient and powdered filler Compositions for dressing seed, for example, may comprise 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 or dimethylformamide).
The compositions may also be in the form of dispersible powders, granules or grains comprising a wetting agent to facilitate the dispersion in liquids of the powder or grains which may contain also fillers and suspending agents.
The aqueous dispersions or emulsions may be prepared by dissolving the active ingredient(s) in an organic solvent optionally containing wetting, dispersing or emulsifying agent(s) and then adding the mixture to water which may also contain wetting, dispersing or emulsifying agent(s) Suitable organic solvents are ethylene dichloride, isopropyl alcohol, propylene glycol, diacetone alcohol, toluene, kerosene, methylnaphthalene, the xylenes, 57 - trichloroethylene, furfuryl alcohol, tetrahydrofurfuryl alcohol, and glycol ethers (eg 2-ethoxyethanol and 2- butoxyethanol).
Tbe compositions to be used as sprays may also be in the form of aerosols wherein the formulation is held in a container under pressure in the presence of a propellant, eg fluorotrichloromethane or dichlorodifluoromethane.
The 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 a micro- encapsulated 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 compounds can be used as mixtures with fertilisers (eq 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 the compound of general formula (I) or metal complex thereof.
The compositions may also be in the form of liquid preparations for use as dips or sprays which are generally aqueous dispersions or emulsions containing the active ingredient in the presence of one or more surfactants eg.
wetting agent(s), dispersing agent(s), emulsifying agent(s) or suspending agent(s); or which are spray formulations of the kind suitable for use in electrodynamic spraying techniques The foregoing agents can be cationic, anionic or non-ionic agents Suitable cationic agents are 58 - quaternary ammonium compounds, for example cetyltrimethyl- ammonium 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).
Suitable non-ionic 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 the vegetable gums (for example gum acacia and gum tragacanth).
The 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(s), and the concentrate is to be diluted with water before use These concentrates often should be able to withstand storage for prolonged periods and after such storage be capable of dilution with water in order to form aqueous preparations which remain homogeneous for a sufficient time to enable them to be applied by convent- ional and electrodynamic spray equipment The concentrates may conveniently contain up to 95 %, suitably 10-85 %, for example 25-60 %, by weight of the active ingredient(s).
These concentrates suitably contain organic acids (eg.
alkaryl or aryl sulphonic acids such as xylenesulphonic acid or dodecyl benzenesulphonic acid) since the presence 59 - of such acids can increase the solubility of the active ingredient(s) in the polar solvents often used in the concentrates The concentrates suitably contain also a high proportion of surfactants so that sufficiently stable emulsions in water can be obtained After dilution to form aqueous preparations, such preparations may contain varying amounts of the active ingredient(s) depending upon the intended purpose, but an aqueous preparation containing 0.0005 % or 0 01 % to 10 % by weight of active ingredient(s) may be used.
The compositions of this invention can comprise also other compound(s) having biological activity, eg compounds having similar or complementary fungicidal activity or compounds having plant growth regulating, herbicidal or insecticidal activity.
The other fungicidal compound can be, for example, one which -is capable of combating ear diseases of cereals (eg.
