Synthesis of a thiocarbamoyl alkylidyne complex and caveats associated with the use of [Mo(≡CLi)(CO) 2 (Tp*)] (Tp* = hydrotris(3,5-dimethylpyrazol-1-yl)borate)

Abstract

The successive reactions of [Mo(≡CBr)(CO)2(Tp*)] (1; Tp* = hydrotris(3,5-dimethylpyrazol-1-yl)borate) with nBuLi and N,N′-dimethylthiocarbamoyl chloride provides as intended, via formation of [Mo(≡CLi)(CO)2(Tp*)] (2a), the thiocarbamoyl alkylidyne c
