Abstract

Alkylation of W(OMe)₃Cl₃ with ethyllithium and N,N,N',N'-tetramethylethylenediamine (tmed) affords the tungsten ethene I hydride complex [Li(tmed)]₃[WHfC₂H₄)₄]. The anion possesses an approximate trigonal bipyramidal geometry with the hydride in an equatorial site. The ethene ligands exchange with one another, presumably by means of a Berry pseudorotation process, but exchange of ethene and hydride hydrogen atoms is slow on the NMR time scale.
