Abstract

The reaction of the carbido cluster complex (C₅Me₅)WOs₃(μ₄-C)(μ-H)(CO)₁₁ (1) with 4-ethynyl toluene is investigated. This reaction results in the formation of an alkylidyne compound (C₅Me₅)WOs₃(μ₃-CCHCHTol)(CO)₁₁ (2) with a trans CH=CHTol substituent. Moreover, the corresponding reaction of 1 with 3-phenyl-1-propyne affords an alkenyl carbido cluster (C₅Me₅)WOs₃(μ₄-C)(CHCHCH₂Ph)(CO)₁₀ (3) and another alkylidyne compound with formula (C₅Me₅)WOs₃[μ₃-CC(CH₂Ph)(CH₂)](CO)₁₀ (4). The compounds 3 and 4 are characterized spectroscopically in solution and with single crystal X-ray diffraction in the solid state. The possible mechanism leading to their formation is discussed.
