Abstract

The reaction of the halocarbyne [W(≡CBr)(CO)₂(Tp*)] (Tp*=hydrotris(3,5-dimethylpyrazol-1-yl)borate) with trimethylsilyl-butadiyne, mediated by [Pd(PPh₃)₄] and CuI, affords the first pentadiynylidyne complex [W(≡CC≡CC≡CSiMe₃)(CO)₂(Tp*)]. Desilylation provides a general route to heterobimetallic pentacarbido complexes, including [(Tp*)(CO)₂W(μ-C₅)(PPh₃)₂Ru(η-C₅H₅)] and [(Ph₃P)₂(CO)HIr{(μ-C₅)W(CO)₂(Tp*)}₂].
