摘要：

The reaction of the complex OsH2Cl2(PiPr3)2 with K(CH3CO2) in methanol affords the trihydride OsH3(eta2-O2CCH3)(PiPr3)2. This complex reacts with PhC2H to give the hydride-vinylidene complex OsH(eta2-O2CCH3)(C=CHPh)(PiPr3)2, which catalyzes the dimerization of phenylacetylene to give a mixture of trans-PhC=CCH=CHPh and cis-PhC=CCH=CHPh in a 2:5 molar ratio.
