NOVEL THIAZOLINE DERIVATIVES
The present invention relates to 2-[pyridyl-(31)]-thiazolines and the tertiary and quaternary salts thereof, to processes for producing them, and to their use for combating pests.
The 2-[pyridyl-(3')]-thiazolines have the formula

' R2-f Y\.A-R4 ' (A>n (I)
V
wherein and R2 are each hydrogen, halogen or C^-C^-alkyl,
R^ and R^ are each hydrogen or C-^-C^-alkyl,
A is an inorganic or organic acid, and n is the number 0, 1 or 2, with the proviso that R^, R2, R^ and R^ are not all simultaneously hydrogen.
By halogen in this case is meant fluorine, chlorine, bromine or iodine, particularly however chlorine. The C-^-C^-alkyl groups denoted by R^ to R^ are methyl, ethyl, propyl, isopropyl or n-, i-, sec- or tert-butyl. Preferred in the case of R^ and R2 is the methyl group. Inorganic acids for A are for example: HCl, l^SO^, HBr and H^PO^; and organic acids for A are for example: saturated and
r ? 0
unsaturated mono-, di- and tricarboxylic acids, such as formic acid, acetic acid, oxalic acid, phthalic acid, succinic acid and citric acid.
Preferred compounds of the formula I are those wherein is hydrogen, R£ is chlorine or methyl, and R^ and R^ are each hydrogen, or R-^ and R2 are each hydrogen, R^ is hydrogen, and R^ is methyl or ethyl, or R^ is methyl or ethyl, R^ is hydrogen, A is an inorganic or organic acid, and n is the number 0, 1 or 2.
The compounds of the formula I can be produced by methods known per se, for example as follows:

(iii) (iv)
In the formulae II, III and IV, the symbols R^ to R^ and n have the meanings defined under the formula I.
The processes 1 and 2 are performed at a reaction temperature of between -50°C and +130°C, preferably between -10°C and +100°C, under normal or slightly elevated pressure, and in the presence of a solvent or diluent inert to the reactants.
Suitable solvents and diluents are for example: ethers and ethereal compounds, such as diethyl ether, diisopropyl ether, dioxane or tetrahydrofuran; aliphatic and aromatic
0020
hydrocarbons, especially benzene, toluene and xylenes; and ketones, such as acetone, methyl ethyl ketone and cyclohexanone.
The starting materials of the formulae II, III and IV are known, or they can be produced by methods analogous to known methods.
The compounds of the formula I, and~2-[pyridyl-(3')]-thiazoline and salts thereof, are suitable for combating pests on animals and plants.
The compounds of the formula I, and 2-[pyridyl-(3')]-thiazoline and salts thereof, are thus suitable for combating insects for example of the orders: Lepidoptera, Coleoptera, Homoptera, Heteroptera, Diptera, Thysanoptera, Orthoptera, Anoplura, Siphonaptera, Mallophaga, Thysanura, Isoptera, Psocoptera and Hymenoptera, and phytopathogenic mites and ticks of the order Acarina.
It is to be emphasised in this connection that the stated compounds are characterised both by a strongly marked systemic as well as contact action against sucking insects, especially against sucking insects of the order Homoptera, and particularly against insects of the Aphididae family (for example Aphis fabae, Aphis craccivora and Myzus persicae), which are very difficult to control by means hitherto known. These active substances exhibit also a favourable action against flies, such as Musca domestica, and against mosquito larvae. They are in addition characterised by a broad ovicidal and ovilarvicidal action, and have a valuable action against ectoparasitic mites and ticks, for example of the families: Ixodidae, Argasidae and Dermanyssidae.
The compounds of the formula I, and 2-[pyridyl-(3')]-thiazoline and salts thereof, are used either in an unmodified form or preferably together with auxiliaries customarily employed in formulation practice, and are
200208
thus processed in a known manner for example into the form of emulsion concentrates, directly sprayable or dilutable solutions, diluted emulsions, wettable powders, dusts or granulates, and also encapsulations in for example polymeric substances. The application processes, such as spraying, atomising, dusting, scattering or pouring, and likewise the type of composition, are selected to suit the objects to be achieved and the given conditions.
The formulations, that is to say, the compositions or preparations containing the active substance and optionally a solid or liquid additive, are produced in a known manner, for example by the intimate mixing and/or grinding of the active substances with extenders, such as with solvents, solid carriers and optionally surface-active compounds (tensides).
Suitable solvents are: aromatic hydrocarbons, preferably the fractions Cg to C-^j such as xylene mixtures or substituted naphthalenes, phthalic esters, such as dibutyl-or dioctylphthalate, aliphatic hydrocarbons, such as cyclohexane or paraffins, alcohols and glycols, as well as ethers and esters thereof, such as ethanol, ethylene glycol, ethylene glycol monomethyl or -ethyl ethers, ketones,
such as cyclohexanone, strongly polar solvents, such as N-methyl-2-pyrrolidone, dimethylsulfoxide or dimethyl-formamide, as well as optionally epoxidised vegetable oils, such as epoxidised coconut oil or soybean oil; or water.
The solid carriers used, for example for dusts and dispersible powders, are as a rule natural mineral fillers, such as calcite, talcum, kaolin, montmorillonite or attapulgite. In order to improve the physical properties, it is also possible to add highly dispersed silicic acid or highly dispersed absorbent polymers. Suitable granulated
2 002 08
adsorptive carriers are porous types, for example pumice, ground brick, sepiolite or bentonite; and suitable non-sorbent carriers are materials such as calcite or sand. A large number of pre-granulated materials of inorganic or organic nature can also be used, such as in particular dolomite or ground plant residues.
Suitable surface-active compounds are, depending on the nature of the active substance to be formulated, nonionic, cationic and/or anionic tensides having good emulsifying, dispersing and wetting properties. By 'tensides' are also meant mixtures of tensides.
Suitable anionic tensides are both so-called water-soluble soaps, as well as water-soluble, synthetic, surface-active compounds.
Soaps which may be mentioned are the alkali metal, alkaline-earth metal or optionally substituted ammonium salts of higher fatty acids ' ^0r examP-'-e sodium or potassium salts of oleic or stearic acid, or of natural fatty acid mixtures, which can be obtained for" example from coconut oil or tallow oil. Also to be mentioned are the fatty acid-methyl-taurine salts.
So-called synthetic tensides are however more frequently used, particularly fatty sulfonates, fatty sulfates, sulfonated benzimidazole derivatives or alkylarylsulfonates. The fatty sulfonates or sulfates are as a rule in the form of alkali metal, alkaline-earth metal or optionally substituted ammonium salts, and contain an alkyl group having 8 to 22 C atoms, 'alkyl' including also the alkyl moiety of acyl groups, for example the Na or Ca salt of ligninsulfonic acid, of dodecylsulfuric acid ester or of a fatty alcohol sulfate mixture produced from natural fatty acids. Included among these are also the salts of sulfuric acid esters and sulfonic acids of fatty alcohol ethylene oxide adducts.
:2 0 0 2 0
The sulfonated benzimidazole derivatives preferably contain 2 sulfonic acid groups and a fatty acid group having 8 - 22 C atoms. Alkyarylsulfonates are for example the Na, Ca or triethanolamine salts of dodecylbenzenesulfonic acid, of dibutylnaphthalenesulfonic acid or of a naphthalenesulfonic acid-formaldehyde condensation product. Also suitable are corresponding phosphates, for example salts of the phosphoric ester of a p-nonylphenol-(4-14)-ethylene oxide adduct.
Suitable nonionic tensides are in particular polyglycol ether derivatives of aliphatic or cycloaliphatic alcohols, saturated or unsaturated fatty acids and alkylphenols,
which can contain 3 to 30 glycol ether groups and 8 to 20 carbon atoms in the (aliphatic) hydrocarbon radical and 6 to 18 carbon atoms in the alkyl moiety of the alkylphenols
Further suitable nonionic tensides are the water-soluble polyethylene oxide adducts, which contain 20 to 250 ethylene glycol ether groups, and 10 to 100 propylene glycol ether groups, with polypropylene glycol, ethylene-diaminopolypropylene glycol and alkylpolypropylene glycol having 1 to 10 carbon atoms in the alkyl chain. The compounds mentioned usually contain 1 to 5 ethylene glycol units per propylene glycol unit. Examples of nonionic tensides which may be mentioned are: nonylphenol-polyethoxyethanols, castor oil polyglycol ethers, polypropylene/polyethylene oxide adducts, tributylphenoxy-polyethoxyethanol, polyethylene glycol and octylphenoxy-polyethoxyethanol. Suitable also are fatty acid esters of polyoxyethylenesorbitan, such as polyoxyethylene-sorbitan-trioleate.
In the case of the cationic tensides, they are in particular quaternary ammonium salts which contain as N-substituents at least one alkyl group having 8 to 22 C atoms and, as further substituents, lower, optionally
2002
halogenated alkyl, benzyl or lower hydroxyalkyl groups. The salts are preferably in the form of halides, methyl sulfates or ethyl sulfates, for example stearyltrimethyl ammonium chloride or benzyldi(2-chloroethyl)ethylammonium bromide.
The tensides customarily used in formulation practice are described, inter alia, in the following publication: "Mc Cutcheon's Detergents and Emulsifiers Annual", MC Publishing Corp., Ringwood, New Jersey, 1979.
The pesticidal preparations contain as a rule 0.1 to 99%, particularly 0.1 to 95%, of active substance , 1 to 99.97o of a solid or liquid additive, and 0 to 25%, especially 0.1 to 25%, of a tenside. Whereas commercial products are preferably in the form of concentrated compositions, the compositions employed by the end-user are as a rule diluted.
The compositions can also contain additives such as stabilisers, antifoam agents, viscosity regulators, binders and adhesives, as well as fertilisers or other active substances for obtaining special effects.
