Abstract
Various substituted ortho-alkyl anilines are prepared by electrolytic desulfurization of various benzyl sulfides, sulfoxides and sulfones, e.g. 2-methyl-6-trifluoromethylaniline is prepared from 2-amino-3-trifluoromethylbenzyl sulfides, sulfoxides and sulfones. The processes are conducted in concentrated aqueous quaternary ammonium hydroxide, as well as in aprotic media. The substituted anilines obtained are useful as intermediates for herbicide compounds.
