Abstract
1,175,002. Alkyl mercapto anilines. BADISCHE ANILIN- & SODA-FABRIK A.G. 3 Feb., 1967 [4 Feb., 1966], No. 5276/67. Heading C2C. The invention comprises a N,N-di-substituted p-alkylmercaptoaniline of the formula in which R<SP>1</SP> and R<SP>2</SP> denote aliphatic, cycloaliphatic or araliphatic radicals and may, together with the nitrogen atom to which they are attached, form a 5- to 7-membered heterocyclic ring and R<SP>3</SP> denotes an alkyl radical and a process for the preparation thereof wherein an N,N-disubstituted aniline of the formula in which R 1 and R 2 have the meanings given above is reacted with a dialkyl sulphoxide and an acid chloride at a temperature of from 0‹ to 50‹ C., the reaction product is decomposed by heating to 100‹ to 150‹C. in the presence or absence of a primary or secondary amine, a N,N-disubstituted carboxylic acid amide or a N-alkylated lactam and the decomposition product is treated with an alkali. R<SP>1</SP> and R<SP>2</SP> with the nitrogen to which they are attached and together with an oxygen atom, or a sulphur atom or a tertiary nitrogen atom may form a 5- to 7-membered heterocyclic ring. The preparations of N,N-dimethyl-, N,N-tetramethylene-, N-ethyl-N-#-cyanoethyl-, N-ethyl- N-#-methoxy ethyl- and N,N-diethyl-p-methyl mercapto anilines are described.
