Abstract

We report solvent and electrolyte effects on the electrocatalytic oxidation of H2 using Ni(PCy 2NR′ 2)2 (R = Bn, tBu) complexes. A turnover frequency of 46 s-1 for Ni(PCy 2N Bn 2)2 was obtained using 0.2 M [ nBu4N][BF4] in THF. A turnover frequency of 51 s-1 was observed for Ni(PCy 2N tBu 2)2 using 0.2 M [nBu 4N][B(C6F5)4] in fluorobenzene. These observations, in conjunction with previous studies, indicate nitrile binding inhibits catalysis supported by Ni(PCy 2N Bn 2)2. This journal is
