Abstract

The successive reactions of [Mo(≡CBr)(CO)₂(Tp*)] (Tp* = hydrotris(3,5-dimethylpyrazol-1-yl)borate) with ⁿBuLi and ClAPh₃ (A = Ge, Sn, Pb) afford the carbyne complexes [Mo(≡CAPh₃)(CO)₂(Tp*)] but fail in the case of ClCPh₃ and ClSiPh₃. The silicon analogue [Mo(≡CSiPh₃)(CO)₂(Tp*)] may, however, be obtained via a multistep Fischer-Mayr synthesis. [Mo(≡CPbPh ₃)(CO)₂(Tp*)] is the first example of a plumbyl alkylidyne complex.
