Abstract

This review deals with organic reactions which are promoted by indium metal or indium salts, with a focus on recent advances in stoichiometric and catalytic pathways. Applications to transmetalations, cross-coupling reactions and carboindation, in which an organoindium species may be postulated, are highlighted, as well as the reactions in which a radical is the key intermediate. Special attention is placed on the role of indium metal as a reducer, and on the Lewis acidity of indium salts in catalytic processes.
