摘要
The complex [Ru-2(mu-CO)(CO)(4)(mu-dppm)(2)] is more active than mononuclear ruthenium complexes as a catalyst for decomposition of formic acid to CO2 and H-2; under conditions of highest activity, a coordinatively unsaturated diruthenium dihydride [Ru2H(mu-H)(mu-CO)(CO)(2)(mu-dppm)(2)] is present and can be isolated from solution.
