Isolation and characterization of a vanadium ethylidyne complex. The crystal structure of [(Cy2N)2Li(µ3-O)(µ2,η1:η1CMe) an unusual V2LiO cluster
Abstract
Reaction of VCI2(TMEDA)2[TMEDA =N,N,N′,N′-tetramethylenediannine] with Cy2NH [Cy = cyclohexyl] and BunLi in tetrahydrofuran led to the formation of a complicated mixture of products from which a dinuclear ethylidyne complex [(Cy2N)2V]2(µ3η1-O)(µ2,η1:η1-CMe)1was isolated
