The new fluorocarbynes [M([triple bond, length as m-dash]CF)(CO)(Tp*)] (M = Mo, W; Tp* = tris(dimethylpyrazolyl)borate) arise from electrophilic fluorination of the lithiocarbynes [M([triple bond, length as m-dash]CLi)(CO)(Tp*)] with FN(SOPh). The reactions of [W([triple bond, length as m-dash]CF)(CO)(Tp*)] with [AuCl(SMe)] and PhICl afford the first μ-fluorocarbyne complex [WAu(μ-CF)Cl(CO)(Tp*)] and the first high oxidation state fluorocarbyne [W([triple bond, length as m-dash]CF)Cl(Tp*)], respectively.
新型氟代卡宾[M(≡CF)(CO)(Tp*)]（M = Mo、W；Tp* = 三(二甲基吡唑基)硼酸酯）由锂代卡宾[M(≡CLi)(CO)(Tp*)]与FN(SOPh)发生亲电氟化反应生成。[W(≡CF)(CO)(Tp*)]与[AuCl(SMe)]及PhICl反应，分别得到首个μ-氟代卡宾配合物[WAu(μ-CF)Cl(CO)(Tp*)]和首个高氧化态氟代卡宾[W(≡CF)Cl(Tp*)]。
