A bis-diphosphine nickel complex with tert-butyl functionalized pendant amines Ni(P(Cy)(2)N(t-Bu)(2))(2) has been synthesized. It is a highly active electrocatalyst for the oxidation of hydrogen in the presence of base. The turnover rate of 50 s(-1) under 1.0 atm H(2) at a potential of -0.77 V vs. the ferrocene couple is 5 times faster than the rate reported heretofore for any other synthetic molecular H(2) oxidation catalyst.
一种带有叔丁基官能化侧胺的双膦镍配合物Ni(P(Cy)(2)N(t-Bu)(2))(2)已被合成。它是一种在碱性条件下高效的氢氧化电催化剂。在 -0.77 V 相对于铁氰化钾电对的电势下，在 1.0 atm H2 下，其 50 s-1 的周转率比迄今为止报道的任何其他合成分子 H2 氧化催化剂的速率快 5 倍。
