Abstract

Non-catalytic and catalytic addition reactions were compared in this review, with a special attention paid to the factors controlling selectivity and yields. The scope and limitations of Ni, Pd, Pt, Rh and Au catalysts for the formation of C-S, C-Se and C-Te bonds were discussed with an impact of development of Green chemical methods.
