説明

The reaction of the monocationic triruthenium hexahydride [(Cp‘Ru)3(μ-H)6]X (1; X = 1/2 SO4, BF4, PF6, BPh4) with hydrazine leads to the formation of the mono(μ3-imido) complex (Cp‘Ru)3(μ3-NH)(μ-H)3 (3) and the triruthenium pentahydride complex (Cp‘Ru)3(μ3-H)2(μ-H)3 (2). Complex 1 is in equilibrium with 2 in the presence of NH4X or N2H5X, and complex 1 is regenerated upon treatment of 2 with such a protic salt. Complex 3 further reacts with hydrazine to yield the bis(μ3-imido) complex (Cp‘Ru)3(μ3-NH)2(μ-H) (4) as a result of cleavage of the nitrogen−nitrogen bond, which is formally catalyzed by a proton. Both 3 and 4 undergo hydrogenation to generate 2 together with ammonia. Thus, reductive cleavage of the nitrogen−nitrogen bond of hydrazine leading to ammonia is achieved by the use of the monocationic trinuclear hexahydride complex 1 and dihydrogen under conditions without any added proton source and a reducing agent.
