Group 14 substituted carbyne complexes - an almost complete set: [Mo(≡CAPh 3 )(CO) 2 (Tp*)] (Tp* = hydrotris(dimethylpyrazolyl)borate; A = Si, Ge, Sn, Pb but A ≠ C).

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 analo Show more
