Abstract

A bis-diphosphine nickel complex with tert-butyl functionalized pendant amines [Ni(P^Cy₂N^t-Bu₂) 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 H₂ 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 H₂ oxidation catalyst.
