Cesium carbonate‐catalyzed indium insertion into alkyl iodides and their synthetic utilities in cross‐coupling reactions

Abstract

A catalytic amount of cesium carbonate (10 mol%) was found to be capable of effectively catalyzing the insertion of indium powder into alkyl iodides. The thus‐generated alkyl indium reagents could readily undergo palladium‐catalyzed cross‐coupling reactions with a wide variety of aryl halides, showing compatibility to a range of important functional groups.
