摘要：

The cluster complex [Ru3(mu-H) (mu3,eta2-ampy)(CO)9] (1; Hampy = 2-amino-6-methylpyridine) does not promote the hydrostannation of diphenylacetylene. A study of the sequential reactions of 1 with diphenylacetylene and R3SnH (R = Bu, Ph) and of 1 with R3SnH and diphenylacetylene has allowed the isolation of [RU3(mu-H)(mu3,eta2-ampy)(SnR3)2(CO)8] and of two isomers of [Ru3(mu-H)(mu3, eta2-ampy)(SnR3){mu,eta1:eta2-PhC=C(H)Ph}(CO)7]. The X-ray structures of the latter (R = Ph) have shown that both isomers have the SnPh3 and diphenylalkenyl groups attached to different ruthenium atoms; this may explain why no hydrostannated diphenylacetylene is observed when diphenylacetylene and triorganotin hydrides are allowed to react with complex 1.
