✦ Synopsis

This review narrates the electron transfer reactions of various nickel(III ) and nickel(IV ) complexes reported during the period 1981 until today. The reactions have been categorized mainly with respect to the type of nickel complexes. The reactivity of nickel(III ) complexes of macrocycles, 2,2∞-bipyridyl and 1,10-phenanthroline, peptides and oxime-imine, and of nickel(IV ) complexes derived from oxime-imine, oxime and miscellaneous ligands with various organic and inorganic electron donors have been included. Kinetic and mechanistic features associated with such interactions have been duly analyzed. The relevance of Marcus cross-relation equations in the delineation of the electron transfer paths has also been critically discussed.
