A dicobaloxime in which monomeric Co(III) units are linked by an octamethylene bis(glyoxime) catalyzes the reduction of protons from p-toluenesulfonic acid as evidenced by electrocatalytic waves at -0.4 V vs. the saturated calomel electrode (SCE) in acetonitrile solutions. Rates of hydrogen evolution were determined from catalytic current peak heights (k(app) = 1100 ± 70 M(-1) s(-1)). Electrochemical experiments reveal no significant enhancement in the rate of H(2) evolution from that of a monom ...[more]
