Electron transfer and autoxidation kinetics of the bis(imidazole)bis(dimethylglyoximato)iron(II) complex

Abstract
The properties and reactivity of the bis(imidazole)bis-(dimethylglyoximato)iron(II) complex have been studied based on spectroelectrochemistry, cyclic voltammetry, and stopped-flow kinetics in aqueous solution. The autoxidation reaction was found to be inhibited by the imidazole ligand in excess but susceptible to copper(II) catalysis. In this case a mechanism has been proposed, consisting of a rapid electron transfer followed by the reoxidation of the resulting Cu(I) species by O2.
