The reaction of the new carbene-containing cluster complex Os{sub 3}(CO){sub 11}(C(Et)NMe{sub 2}) (2) with PhC{triple bond}CH has yielded the complex Os{sub 3}(CO){sub 9}({mu}{sub 3}-PhC{sub 2}{l brace}C(Et)(NMe{sub 2}){r brace})({mu}-H) (3, 35%), which contains a triply bridging alkyne ligand with phenyl and ethyl(dimethyliminio)methyl substituents. The product is believed to have been formed by the transfer of the C(Et)NMe{sub 2} carbene ligand in 2 to the {alpha}-carbon atom of a bridging PhC{triple bond}C ligand in an intermediate formed by the activation of PhC{triple bond}CH by the cluster.
