Gallium-Catalyzed Reductive Chlorination of Carboxylic Acids with Copper(II) Chloride

摘要

Described herein is the direct chlorination of carboxylic acids using copper(II) chloride via a gallium(III)-catalyzed reduction in the presence of a hydrosiloxane. During this reductive chlorination, the counteranions of CuCl_2 functioned as a chloride source.
