Fluorocarbyne complexes via electrophilic fluorination of carbido ligands.

ABSTRACT: The new fluorocarbynes [M([triple bond, length as m-dash]CF)(CO)₂(Tp*)] (M = Mo, W; Tp* = tris(dimethylpyrazolyl)borate) arise from electrophilic fluorination of the lithiocarbynes [M([triple bond, length as m-dash]CLi)(CO)₂(Tp*)] with FN(SO₂Ph)₂. The reactions of [W([triple bond, length as m-dash]CF)(CO)₂(Tp*)] with [AuCl(SMe₂)] and PhICl₂ afford the first μ₂-fluorocarbyne complex [WAu(μ-CF)Cl(CO)₂(Tp*)] and the first high oxidation state fluorocarbyne [W([triple bond, length as m-dash]CF)Cl₂(Tp*)], respectively.
