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

Abstract

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 CuCl₂ functioned as a chloride source
