METHYLENEPHOSPHONIUM-IONS: A NEW CLASS OF UNSATURATED ORGANOPHOSPHORUS COMPOUNDS

Gruetzmacher, Hansjoerg,Heim, Udo,Schoenberg, Hartmuth,Pritzkow, Hans

, p. 21 - 24 (2007/10/02)

Methylenephosphonium ions R2P=CR'2+X-, could be prepared by either adding electrophiles to the carbene R2P-C-R' (R = iPr2N, R' = SiMe3) or abstracting chloride from P-halogenated ylides R2PCl=CR'2 (R = tBu, R' = SiMe3 or Aryl).Their structures and reactivity is discussed.
