Abstract
Compounds of the general formula: in which R<1> is a substituted or unsubstituted aryl or alkyl group, R<2> is a substituted or unsubstituted cycloalkyl group, X is an oxygen atom or a methylene group, Y is a hydrogen or halogen atom or an alkyl or alkoxy group, and n is an integer from 1 to 5 are used for pest control, in particular against insects and ticks.
Description
This invention relates to a group of compounds, which may be termed benzyloxime ethers, having interesting pesticidal activity. It also relates to a method of preparing the compounds and to a pesticidal composition comprising one or more of the compounds.
The present invention provides compounds of the following wherein R1 is an optionally-substituted aryl or alkyl group; R is an optionally-substituted cycloalkyl group; X is an oxygen atom or a methylene group; Y is a hydrogen or halogen atom, or an alkyl or alkoxy . group, and n is an integer of 1 to 5.
When R represents an optionally-substituted aryl group in formula I it is preferably a naphthyl group or an optionallysubstituted phenyl group of the following structure: wherein Z is a hydrogen or halogen atom, or an alkyl or alkoxy group, and m is an integer of 1 to 5. Generally speaking, better insecticidal activity has been observed when there is a substituent in the 4 position and m is 1 or 2; e.g. Z may be e.g. chlorine, bromine, fluorine, methyl, ethyl, tertiary-butyl or methoxy. - 3 When R1 represents an optionally-substituted alkyl group, it can be a straight or branched-chain alkyl group and may have as substituent or substituents one or more halogen atoms, or alkoxy or aryl groups, e.g. chlorine, bromine, fluorine, methoxy or phenyl. The alkyl group preferably contains up to 10 carbon atoms.
The substituent Y preferably represents a hydrogen atom but can also be an alkyl or alkoxy group of 1 to 4 carbon atoms or a halogen atom, e.g. chlorine, fluorine or bromine atom. ρ The group R preferably represents a substituted or unsubstituted cycloalkyl group of 3 to 6 carbon atoms, e.g. a cyclopropyl or eyclobutyl group, for example a oyclopropyl group having the following formula wherein Rg and R^ both represent hydrogen atoms, alkyl groups having from 1 to 6 carbon atoms, especially methyl, or halogen atoms, especially chlorine or bromine atoms; or R„ and R. a d together represent an alkylene group having from 2 to 6, especially 3, carbon atoms; or R~ represents a hydrogen atom a and R& represents an alkenyl group having from 2 to 6 carbon atoms, especially an isobutenyl group, or an haloalkenyl group having from 2 to 6 carbon atoms and from 1 to 3 chlorine or bromine atoms, especially a mono- or dichlorovinyl group; 43333 Re and R^ both represent hydrogen atoms or alkyl groups having 1 to 6 carbon atoms, especially methyl, or Rc is hydrogen and R^ is an alkenyl group having from 2 to 6 carbon atoms, especially an isobutenyl group, or a haloalkenyl group having from 2 to 6 carbon atoms and from 1 to 3 chlorine or bromine atoms, especially a mono- or dichlorovinyl group; or Re and Rd together represent an alkylene group having from 2 to 6, especially 3 carbon atoms. A better level of pesticidal activity has generally been noted 2 where R in the general formula I represents an unsubstituted cyclopropyl group.
Because of their high level of activity against the corn-ear worm (Heliothis zea) the following group of compounds are preferred:- wherein R^ is phenyl, chlorophenyl, dichlorophenyl, bromophenyl, dibromophenyl, fluorophenyl, difluorophenyl, methylphenyl, dimethylphenyl, methoxyphenyl, butylphenyl, ethylphenyl or naphthyl; and Y is hydrogen, chlorine, fluorine or bromine.
It will be appreciated that the compounds according to the invention exhibit geometrical isomerism about the oximic double bond and, accordingly, the invention also extends to these individual isomers and to mixtures thereof. It has been found that, in general terms, the isomer in which R (the optionally-substituted cycloalkyl group) and the 3-substituted - 5 10 benzyloxy group in the compounds of formula I are in a syn relationship about the double bond is more insecticidallyactive than the isomer in which the two groups are in anti relationship; more correctly the nomenclature of these two geometric isomers should be referred to as the E- and Z-isomers, the E-isomer being the more active form. Accordingly, the preferred form of the compounds according to the invention is the E-isomer or a mixture of the two isomers in which the E-isomer predominates.
The compounds according to the invention may be prepared by methods known for the preparation of oxime ethers. A ketoxime of formulas'C = NOH (V) 2 wherein R and R have the meanings previously defined, is a preferred starting material. A method for the preparation of compounds of the invention comprises reacting an alkali metal salt of a ketoxime of formula V with a substituted benzyl halide of formulas- (γ) Q - CH2—(VI) wherein X, Y and n have the meaninge previously defined and Q is a halogen, preferably bromine,atom. The reaction is preferably carried out in the presence of a polar aprotic solvent; 6 333 particularly suitable solvents are anhydrous acetonitrile, dimethylformamide in toluene, or tetrahydrofuran. Reaction temperatures are generally in the range 60-150°C preferably in the range 100-110°C and reaction time3 of 2 to 10 hours may be used. Alternatively the reaction of the alkali metal salt of a ketoxime of formula V with a substituted benzyl halide of formula VI may be carried out in a two-phase organic/inorganic system in the presence of a phase transfer catalyst. The phase transfer catalyst may be any reagent which will accelerate interphase reactions in organicinorganic two-phase systems. The alkali metal salt of the ketoxime of formula V may be prepared by the reaction of an alkali metal hydride with the ketoxime, for example, sodium hydride, or by reaction of aqueous potassium or sodium hydroxide with the ketoxime. Under normal conditions the alkali metal salt of the ketoxime is prepared in situ.
The benzyl oxime ethers of the invention are of interest as pesticides, in particular as insecticides, tickicides and acaricides for agricultural and domestic outlets. The invention therefore includes within its scope pesticidal compositions comprising a carrier and/or a surface-active agent together with, as active ingredient, a benzyl oxime ether of formula I. The invention also includes a method of combating insect, tick and/or acarid pests at a locus which comprises applying to the locus a pesticidally effective amount of a benzyl oxime ether of the invention or composition containing such a compound. 633 3 The term 'carrier' as used herein means a material, which may be inorganic or organic and of synthetic or natural origin, with which the active compound is mixed or formulated to facilitate its application to the plant, seed, soil or other object to be treated, or its storage, transport or handling. The carrier may be a solid or a liquid. Any of the materials usually applied in formulating pesticides, herbicides, or fungicides may be used as the carrier.
Suitable solid carriers are natural and synthetic clays 10 and silicates, for example, natural silicas such as diatoraaceous earths; magnesium silicates, for example, tales; magnesium aluminium silicates, for example, attapulgites and vermiculites; aluminium silicates, for example, kaolinites, montmorillinifces and micas; calcium carbonates; calcium sulphate; synthetic hydrated silicon oxides and synthetic calcium or aluminium silicates; elements for example, carbon and sulphur; natural and synthetic resins such as, for example, coumarone resins, polyvinyl chloride and styrene polymers and copolymers; solid polychlorophenols; bitumen; waxes such as for example, beeswax, paraffin wax, and chlorinated mineral waxes; and solid fertilisers, for example, superphosphates.
Suitable liquid carriers are water, alcohols, for example, isopropanol and glycols; ketones for example, acetone, methyl ethyl ketone, and cyclohexanone; ethers; aromatic hydro25 carbons, for example, benzene, toluene and xylene; petroleum fractions, for example, kerosine and light mineral oils; 4S33S - 8 chlorinated hydrocarbons, for example, carbon tetrachloride, perchloroethylene, trichloroethane; and liquefied normally vaporous, gaseous compounds. Mixtures of different liquids are often suitable.
The surface-active agent may be an emulsifying agent or a dispersing agent or a wetting agent; it may be nonionic or ionic. Any of the surface-active agents usually applied in formulating pesticides, herbicides or fungicides, may be used. Examples of suitable surface-active agents are the sodium or calcium salts of polyacrylic acids and lignin sulphonic acids; the condensation products of fatty acids or aliphatic amines or amides containing at least 12 carbon atoms in the molecule with ethylene oxide and/or propylene oxide; fatty acid esters of glycerol, sorbitan, sucrose or pentaerythritol; condensates of these with ethylene oxide and/or propylene oxide; condensation products of fatty alcohols or alkyl phenols for example p-octylphenol or p-ootylcresol, with ethylene oxide and/or propylene oxide; sulphates or sulphonates of these condensation products; alkali or alkaline earth metal salts, preferably sodium salts, or sulphuric or sulphonic acid esters containing at least 10 carbon atoms in the molecule, for example, sodium lauryl sulphate, sodium secondary alkyl sulphates, sodium salts of sulphonated castor oil, and sodium alkylaryl sulphonates such as sodium dodecylbenzene sulphate; and polymers of ethylene oxide and copolymers of ethylene oxide and propylene oxide. - 9 The compositions of the invention may be formulated as wettable powders, dusts, granules, solutions, emulsifiable concentrates, emulsions, suspension concentrates and aerosols. Wettable powders are usually compounded to contain 25. 50 and 75? of toxicant and usually contain, in addition, to solid carrier, 3-10% w of a dispersing agent and, where necessary, 0-10? w of stabiliser(s) and/or other additives such as penetrants or stickers. Dusts are usually formulated as a dust concentrate having a similar composition to that of a wettable powder but without a dispersant, and are diluted in the field with further solid carrier to give a composition usually containing £-10? w of toxicant. Granules are usually prepared to have a size between 10 and 100 BS mesh (1.670-0.152 mm) and may be manufactured by agglomeration or impregnation techniques. Generally granules will contain £-25? w toxicant and 0-10? w of additives such as stabilisers, slow release modifiers and binding agents. Emulsifiable concentrates usually contain, in addition to the solvent and, when necessary, co-solvent, 10-50? w toxicant, 2-20? w/v emulsifiers and 0-20? w/v of appropriate additives such as stabilisers, penetrants and corrosion inhibitors. Suspension concentrates are compounded so as to obtain a stable, non-sedimenting flowable product and usually contain 10-75? w toxicant, 0.5-15? w of dispersing agents, 0.1-10? w of suspending agents such as protective colloids and thixotropic agents, 0-10? w of appropriate additives such as defoamers, corrosion inhibitors, 46335 -10r stabilisers, penetrants and stickers, and as carrier, water or an organic liquid in which the toxicant is substantially insoluble; certain organic solids or inorganic salts may be dissolved in the carrier to assist in preventing sedimentation or as antifreeze agents for water.
Aqueous dispersions and emulsions, for example, compositions Obtained by diluting a wettable powder or a concentrate according to the invention with water, also lie within the scope of the present invention. The said emulsions may be of the water-in-oil or of the oil-in-water type, and may have a thick 'mayonnaise'like consistency.
The compositions of the invention may also contain other ingredients, for example, other compounds possessing pesticidal, herbicidal or fungicidal properties.
The invention is further illustrated in the following examples.

Spodoptera littoralis (S.l.) Hellothis zea (H.z.) Ticks:- Boophilus microplus (B.m.) The test methods employed for each species appear below:(i) Musca domestica (M.d.) A 0.4? by weight solution in acetone of the compound to be tested was prepared and taken up in a micrometer syringe. Two to three day old adult female houseflies (musca domestica) were anaesthetized with carbon dioxide, and 1 pi of the test solution was applied to the ventral side of the abdomen of each fly, 20 flies being tested. The treated flies were held in glass jars covered with paper tissue held by an elastic band. Cotton-wool pads soaked in dilute sugar solution were placed on top of the tissue as food. After 24 hours the percentage of dead and moribund flies were recorded, (i i) Spodoptera littoralis (S.l.) Pairs of leaves were removed from broad bean plants and placed on filter paper inside plastic petri dishes. The leaves were sprayed on the undersurface with a formulation containing 20? by weight of acetone, 0.05? by weight of TRITON X-100 (TRITON" is a registered trade mark) as wetting agent and 0.4$ by weight of the compound to be tested. Varying concentrations were obtained by diluting the formulation After spraying, the leaves were left for - 1 hour drying period and then each leaf pair was infested with ten larvae of the Egyptian cotton leafworm (Spodoptera littoralis). After 24 hours the percentage of dead and moribund larvae were recorded. (iii) Boophilus microplus (B.m.) The compounds to be tested were formulated as solutions or fine suspensions in acetone containing 10$ by weight of polyethylene glycol having an average molecular weight of 400. The formulations contained 0.1$ by weight of the compound to be tested. 1 ml of the above-mentioned solution was applied evenly to a filter paper situated inside a petri dish. After the paper was sufficiently dry it was folded in half and partly crimped along the outer edge to form a packet. About 80-100 larval ticks (Boophilus microplus) were transferred into the packet which was then sealed completely. The packets were placed inside an incubator, maintained at 27°C and 80$ relative humidity, before assessing mortality 24 hours later. (iv) Heliothis zea (H.z.) A 0.2$ by weight solution of the compound to be tested was prepared by adding 2 ml of a 1$ acetone solution to 8 ml Of 0.05$ ATLOX 1O45A (ATLOX is a trade mark) solution. The cut broad been plant was sprayed with 4 ml of test solution 46338 - 20 using a hand sprayer. Immediately after spraying 5 larvae of the corn earworm (Heliothis zea) were transferred to each plant which was inserted into water through the centre hole of a test board and covered with a wire screen. 44-46 hours after spraying the percentage of dead and moribund larvae were recorded.
The results are shown In Table III in which the test species are identified by the initials noted above and the activity of each compound is expressed in the form of their Toxicity Index (T.I.) which is calculated frora the following equation:Toxicity Index (T.I.) =LC50 of ethyl Parathion LCgQ of test compound wherein is the lethal concentration required to kill 50? of the test species.
