Electron transfer, in organonickel complexes of α-diimines:: Versatile redox catalysts for C-C or C-P coupling reactions -: A review

Organonickel complexes with alpha-diimine ligands play an important role in electrocatalytic C-C or C-P cross coupling reactions. The review summarises recent insights into the reaction mechanisms of such reactions obtained by electrochemical experiments, electrosynthesis and spectroelectrochernistry (UV-vis-NIR or EPR). The (formal) oxidations states of the involved nickel species range from Ni(0) to Ni(III). (c) 2007 Elsevier B.V. All rights reserved.
