ABSTRACT:
The invention relates to 2-alkylmercapto-4-(trifluoromethyl)benzoic esters of the formula (II), in which R.sup.1 and R.sup.2 are, independently of each other, (C.sub.1 -C.sub.6) alkyl, and a process for their preparation, which comprises reacting 3,4-dichlorobenzotrifluoride electrochemically at an anode with CO.sub.2 to give 2-chloro-4-(trifluoromethyl)-benzoate, converting it into the corresponding benzoic ester of the formula (I), and then reacting it with an alkylmercaptide R.sup.2 S.sup.e. ##STR1##
