摘要：

The attachment of sigma-2-thienyl and sigma-2-benzothienyl ligands (but not sigma-3-thiophenyl ligands) to W2(6+) containing centres leads to the stepwise opening of the five-membered ring to generate, in the presence of tert-butyl alcohol, a novel thiolato-mu-alkylidyne metallocycle in W2(OBut)5(mu-SC4H4)(eta1-2-SC4H3), which has been structurally characterized; the intermediate W2(OBut)4(mu-SC4H3)(eta1-2-SC4H3), which contains a bridging thiolato-vinylidene metallocycle has been characterized by NMR spectroscopy.
