GB964689A - Aromatic esters of quaternary ammonium alkyl sulphonic acids and fungicidal compositions - Google Patents

Abstract

The invention comprises compounds of the formula: <FORM:0964689/C1/1> in which Ar is an aromatic radical which may be substituted by one or more halogen atoms, alkyl, nitro, hydroxyl, acyl, formyl, methoxy, ethoxy, nitrile, acylamino or thiocyanate groups, X is hydrogen, an alkyl radical or halogen and X2 is hydrogen, R1, R2 and R3 are alkyl radicals and Y is an anion, such as I-, Cl-, Br-, CH3OSO3-, CH2 = CHSO3-, acetate or sulphate. The compounds may be made by reacting a sulphonic ester ArOSO2-CH=CH2 with a secondary amine R1.NH.R2 forming Ar.OSO2.CH2.CH2 N.R1(R2) followed by alkylation with YR3. An example describes the reaction of the phenyl ester of N-dimethyl-b -aminoethane sulphonic acid with dimethyl sulphate to form the phenyl ester of N-trimethyl b -aminoethanesulphonic acid methyl sulphate. Suitable starting materials are listed in which the phenyl nucleus is substituted as indicated above. Specification 910,377 is referred to.ALSO:Fungicidal compositions comprise a compound of the formula <FORM:0964689/A5-A6/1> in which Ar is an aromatic radical which may be substituted by one or more halogen atoms, alkyl, nitro, hydroxyl, acyl, formyl, methoxy, ethoxy, nitrile, acylamino or thiocyanate groups, X1 is hydrogen, an alkyl radical or halogen and X2 is hydrogen, R1, R2 and R3 are alkyl radicals and Y is an anion, such as I-, Cl-, Br-, CH3OSO3-, CH2=CHSO3-, acetate or sulphate, with liquid or solid diluents or carriers, such as water and organic liquids or talc. Dispersing and wetting agents may be present and other active substances with acaricidal, insecticidal, ovicidal, herbicidal, fungicidal or bactericidal action may be added. Examples are given. Specification 910,377 is referred to.
