Abstract
The new fluorocarbynes [M(![[triple bond, length as m-dash]](https://www.rsc.org/images/entities/char_e002.gif)
CF)(CO)2(Tp*)] (M = Mo, W; Tp* = tris(dimethylpyrazolyl)borate) arise from electrophilic fluorination of the lithiocarbynes [M(CLi)(CO)2(Tp*)] with FN(SO2Ph)2. The reactions of [W(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(CF)Cl2(Tp*)], respectively.
