摘要：

The behaviour of the iron clusters Fe3(CO)9(mu-CO)(mu-3-PR) (R = (i)Pr, PNEt2), (mu-H)Fe3(CO)9(mu-3-P-p-C6H4OMe), Fe3(CO)9(mu-3-P(t)Bu)2 and that of the 62 electron Ru4(CO)13(mu-3-PPh) complex in the homogeneous hydrogenation of diphenylacetylene and isomerization of cis-stilbene have been examined. The iron derivatives show only a moderate activity in hydrogenation and isomerization. The ruthenium cluster shows considerable activity in both processes, but the outcome depends markedly on the reaction time and temperature. The variations are explained in terms of the reactivity of the cluster frame.
