摘要：

Treatment of Cp*W(CO)(3)(C=CCH(2)OMe) with Os-3(CO)(10)(NCMe)(2) in refluxing toluene afforded two cluster compounds (2a,b) with identical molecular formula CP*WOs3(CO)(11)-(C=CCH(2)OMe). Both compounds contain a butterfly skeletal arrangement and a multisite bound mu(4)-eta(2)-acetylide ligand. Complex 2a can be converted to 2b by relocating the Cp*W-(CO)(2) fragment from the hinge site to a wingtip position. The acetylide migration in 2b and the kinetic studies of the conversion between 2a and 2b are presented.
