Synthesis of Thiol Esters by Carboxylic Trichlorobenzoic Anhydrides

Abstract
Thiocarboxylic S-esters were obtained rapidly and in high yields by treating the mixed anhydrides prepared from 2,4,6-trichlorobenzoyl chloride and carboxylic acid, with various types of thiols in the presence of 4-dimethylaminopyridine.
