摘要：
We report a synthetic nickel complex containing proton relays, [Ni((P2N2C6H4OH)-N-Ph)(2)](BF4)(2) ((P2N2C6H4OH)-N-Ph = 1,5-bis(p-hydroxyphenyl)-3,7- diphenyl-1,5-diaza-3,7-diphosphacyclo-octane), that catalyzes the production of H-2 in aqueous acetonitrile with turnover frequencies of 750-170 000 s(-1) at experimentally determined overpotentials of 310-470 mV.
