A New Convenient Preparation of Thiol Esters Utilizing <i>N</i>-Acylbenzotriazoles

Abstract

Diverse thiol esters were synthesized in good to excellent yields (76-99%) by reactions of thiophenol, benzyl mercaptan, ethyl­ mercaptoacetate, and mercaptoacetic acid with N-acylbenzo­triazoles under mild conditions. These results demonstrate the utility of N-acylbenzotriazoles as mild S-acylating agents, especially when the corresponding acid chlorides are not readily available.
