摘要：

The 48-electron complex [Ru3(mu-H)(mu3-eta2-ampy) (CO)9] (1; ampy = 2-amino-6-methylpyridinate) reacts with molecular hydrogen (110-degrees-C, 1 atm) to give the 92-electron hexanuclear hexahydrido derivative [Ru6-(mu-H)6(mu3-eta2-ampy)2(CO)14] (2). This hexanuclear compound undergoes CO substitution instead of ligand addition when treated with P(p-tolyl)3 to give the complex [RU6(mu-H)6(mu3-eta2-ampy)2{P(p-tolyl)3}2(CO)12] (3), which has been characterized by X-ray diffraction methods. Compound 2 is an efficient catalyst precursor for the homogeneous hydrogenation of diphenylacetylene to cisstilbene under mild conditions (50-degrees-C, 1 atm).
