Abstract

Pincer 1,3-bis((diphenyl)phosphinoxy)phenyl nickel(II) complexes (PhPOCOPPh)NiX [X = I, OC(O)CH3, OC(O)CF3] were studied as potential catalysts of electrochemical hydrogen evolution reaction (HER) on a glassy carbon electrode in acetonitrile in the presence of proton donor HBF4 using cyclic voltammetry. It is shown that all the complexes can act as precatalysts for HER. A mechanism for HER involving these complexes is proposed
