ABSTRACT:
Ortho-alkylanilines are prepared by catalytic hydrodesulfurization of ortho-aminobenzyl sulfides using a cobalt-molybdenum oxide catalyst. For example, 2-methyl-6-trifluoromethylaniline is prepared by catalytic hydrodesulfurization of 3-trifluoromethyl-2-aminobenzyl sulfides. The substituted anilines prepared by the method of this invention are useful as intermediates in the synthesis of compounds shown to have herbicidal activity.
