An anionic nucleophilic d⁴ carbyne complex

Hill, Anthony F; Kong, Richard Y


The reaction of the complex [W≡CH)Br(CO)₂(dcpe)] (dcpe = 1,2-bis(dicyclohexylphosphino)ethane) with ͭ BuLi affords the intermediate anionic neopentylidyne complex Li[W(≡CtBu)(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≡CtBu)(X)(CO)₂(dcpe)] (X = Cl, Br, EPh, SnMe₃).
