Pentadiynylidyne and Pentacarbido Complexes |
|
| Authors: | Anthony F Hill Richard A Manzano |
| 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]. |
