摘要：

Treatment of the tungsten dinitrogen complex cis-[W(N-2)(2)(PMe2Ph)(4)] (Me = methyl, Ph = phenyl) with an equilibrium mixture of [RuCl(dppp)(2)]X and trans-[RuCl(eta(2)-H-2)(dppp)(2)]X [X = BF4, PF6, or OSO2CF3; dppp = 1,3-bis(diphenylphosphino)propane] under 1 atmosphere of dihydrogen at 55 degrees Celsius for 24 hours gave NH3 in moderate yield. The same reaction in the presence of acetone produced acetone azine in high yield. None of these reactions proceeded in the absence of dihydrogen.
