2-ALKYLMERCAPTO-4-(TRIFLUORO-METHYL)BENZOIC ESTERS AND A PROCESS FOR THEIR PREPARATION

摘要

2-Alkylmercapto4-(trifluoromethyl)benzoic esters and a process for their preparation The invention relates to 2-alkylmercapto4-(trifluoromethyl)benzoic esters of theformula (II), in which R1 and R2 are, independently of each other, (C1-C6) alkyl, and a process for their preparation, which comprises reacting 3,4dichlorobenzotrifluoride electrochemically at an anode with CO2 to give 2-chloro-4- (trifluoromethyl)-benzoate, converting it into the corresponding benzoic ester of the formula (1), and then reacting it with an alkylmercaptide R2Se.
