Abstract

The reaction of the methylidyne complex [W(≡CH)Br(CO)₂(dcpe)] (dcpe = 1,2-bis(dicyclohexylphosphino)ethane) with ^tBuLi affords the intermediate anionic neopentylidyne complex Li[W(≡C^tBu)(CO)₂(dcpe)] which acts as a metal-based nucleophile towards ^tBuCl, ^tBuBr, Ph₂E₂ (E = S, Se, Te) and ClSnMe₃ to afford the new carbyne complexes [W(≡C^tBu)(X)(CO)₂(dcpe)] (X = Cl, Br, EPh, SnMe₃).
