Abstract: Sulphene amides of general formula <FORM:0642534/IV (b)/1> wherein R-S- represents the residue obtainable on the removal of hydrogen from the -SH group of a sulphydryl compound and <FORM:0642534/IV (b)/2> represents the residue obtained by the removal of hydrogen from a primary or secondary amine, are prepared by reading a sulphydryl compound and an amine having at least one replaceable hydrogen in the amino group in an aqueous medium, or in the presence of organic solvents, containing an oxidizing agent such as an alkali hypochlorite, a halogen, sodium ferricyanide and hydrogen peroxide (see also U.S.A. Specification 2,045,888).  Specified sulphydryl compounds are the mercapto-alkyl-thiazoles, mercapto-aryl- and arylene-thiazoles, mercapto-thiazolines, mercapto-oxazoles and oxazolines, mercapto thiodiazoles, mercapto-thiazines, dithiocarbamic acids, di- and tri-thiocarbonic acids, xanthogenic acids; their corresponding metal salts and disulphides.  Specified amines are methyl-, ethyl-, butyl-, isobutyl-, amyl- and cyclohexyl-amines; aniline, o-, m-, p-toluidines, xylidenes, benzylamine, dimethylamine, diethyl-, methylethyl-, dibutyl- and diisobutyl-amines; piperidine, morpholine, thiomorpholine, dicyclohexylamine, N - methylaniline, N - ethylaniline, diphenylamine, methylbenzylamine, dibenzylamine and methylnaphthylamines.ALSO:A pesticidal composition comprises a sulphene amide of general formula <FORM:0642534/VI/1> wherein R-S- represents the residue obtained by the removal of the hydrogen atom from the -SH group of a sulphydryl compound and <FORM:0642534/VI/2> represents the residue obtained by the removal of hydrogen from a primary or secondary amine and a carrier.  The sulphene amides are prepared by the oxidation of a sulphhydryl compound in the presence of a primary or secondary amine as disclosed in U.S.A Specification 2,045,888.  Specified sulphydryl compounds are mercaptoalkylthiazoles, mercaptoarylenethiazoles, mercaptoarylthiazoles, Mercaptothiazolines, mercaptooxazoles, mercaptothiazines, mercapto oxazolines, mercaptothiodiazoles, dithiocarbamic acids, dithio-carbonic acids, trithiocarbonic acid, xanthogenic acids, their metal salts and disulphides and the following amines, methylamine, ethylamine, butylamine, isobutylamine, amylamine, cyclohexylamine, aniline, o-m-p-toluidine, xylidine, benzylamine, dimethylamine, diethylamine, methyl ethyl amine, dibutylamine, diisobutylamine, piperidine, morpholine, thiomorpholine, dicyclohexylamine, N-methylaniline, N-ethylaniline, diphenylamine, methylbenzylamine, dibenzylamine, methylnaphthylamines.  The sulphene amides may be admixed with other fungicides, insecticides or bactericides, e.g., metallic arsenicals, fluosilicates, organic thiocyanates, phenothiazine, nicotine, pyrethrum, rotenone and isobutylundecylenamide.  The compositions may be further admixed with bentonite, talc, calcium carbonate and tricalcium phosphate or dispersed in water or petroleum hydrocarbons with the aid of wetting agents such as lauryl alcohol, long-chain alcohol sulphates, sulphated and sulphonated alcohols, sodium salts of sulphated alcohols, sulphonated aliphatic derivatives, sul phonated aromatic or alkyl aryl derivatives, hexahydric alcohols, esters of fatty acids, pine oils and soyabean lecithin. Adhesives such as milk products, flour, gelatin and fish oils may also be present.  Specification 602,259 is referred to.  The Specification as open to inspection under Sect. 91 comprises the compositions in the form of solutions in organic solvents such as ethyl alcohol.  This subject-matter does not appear in the Specification as accepted.
