Introduction

From several decades, indium compounds have attracted the attention of a great number of research groups due to their broad chameleonic behavior. These versatile reagents are widely used in organic chemistry as reducing agents,[1] radical initiators,[2] and Lewis acid catalysts.[3] In particular, organoindium compounds are versatile, mild, relatively stable, and non-toxic in nature. In these reactions, various sensitive functional groups can be used directly without derivatization. In the context of green chemistry, organoindium reagents can undergo reactions in water, which is attractive from both economic and environmental standpoints. Organoindium compounds are versatile reagents for allylation, propargylation, allenylation, umpolung of enones, benzylation, arylation, alkylation, alkenylation and cross-coupling. Apart from these applications, they are also known for Reformatsky, Henry and Barbier-type reactions.[4]
