摘要：

The hydridic complex HRu3(CO)(9)(perpendicular to-C2But) (Complex 1), containing an acetylide coordinated in perpendicular fashion with respect to one edge of the triangular cluster, catalyzes the hydrogenation of alkynes and of 1,4-cyclohexadiene (I,4-CHD) either under homogeneous and under solid-gas conditions. Cluster catalysis is likely to occur; however, under homogeneous conditions, evidence for partial fragmentation of the cluster has also been found. In these conditions, formation of known metallacyclic compounds and of the new dinuclear derivative Ru-2(CO)(6){(HC2But)(C2Ph2)} (Complex 2a) has bean observed: they are presumably inactive byproducts.
