Abstract

Treatment of the tungsten dinitrogen complex cis -[W(N 2 ) 2 (PMe 2 Ph) 4 ] (Me = methyl, Ph = phenyl) with an equilibrium mixture of [RuCl(dppp) 2 ]X and trans -[RuCl(η 2 -H 2 )(dppp) 2 ]X [X = BF 4 , PF 6 , or OSO 2 CF 3 ; dppp = 1,3-bis(diphenylphosphino)propane] under 1 atmosphere of dihydrogen at 55 degrees Celsius for 24 hours gave NH 3 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.
