The reaction of [W([triple bond, length as m-dash]CH)Br(CO) 2 (dcpe)] (dcpe = 1,2-bis(dicyclohexylphosphino)ethane) with BuLi and SiCl 4 affords the trichlorosilyl ligated neopentylidyne complex [W([triple bond, length as m-dash]C Bu)(SiCl 3 )(CO) 2 (dcpe)]. This slowly reacts with H 2 O to afford [W([triple bond, length as m-dash]CCH 2 Bu)Cl 3 (dcpe)] and ultimately H 2 C[double bond, length as m-dash]CH Bu via an unprecedented alkylidyne homologation in which coordinated CO is the source of the additional carbon atom with potential relevance to the Fischer-Tropsch process.
