Abstract

The methylenephosphine MesPC (SiMe3) 2 [(1) Mes= mesityl] is smoothly oxidized by elemental sulphur to the 3-membered ring system Mes [graphic omitted](SiMe3) 2,(3), which, upon treatment with Bun3P, is converted into the 3-co-ordinate phosphorane MesP (S) C (SiMe3) 2,(2); the nearly isostructural nature of compounds (2) and (3) is confirmed by their X-ray crystallographic analyses.
