Abstract
The use of indium salts as catalysts and mediators in addition, cyclization, aromatic electrophilic substitution, nucleophilic substitution, coupling, reduction, rearrangement and polymerization reactions that have appeared in papers published between 2000 and the first half of 2002 is reviewed. InCl3, InBr3, InI3, InCl, InBr, InI, In(OTf)3, and In(NTf)3 are most commonly used indium salts depending on the reaction type and reaction conditions. The use of indium salts, generally, allows the reaction to be carried out under mild conditions, with high yield and high selectivity. Sometimes, an aqueous medium can be used and the catalyst can be reused.
