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.

Radicals: Electronic Structure and Geometry
Accordingly, the structure of a trivalent radical lies between the geometries of carbocations and carbanions. An sp2-hybridized carbocation is trigonal planar, while an sp3-hybridized carbanion is trigonal pyramidal. Here, the difference in geometry is...
