Bis(trifluoromethyl) phosphines RP-(CF 3 ) 2 (R = Me, NEt 2 ) were methylated by MeOSO 2 -CF 3 , yielding the respective phosphonium salts [RP(CF 3 ) 2 Me] + and CF 3 SO 3 -. Deprotonation using MeN P(NEt 2 ) 3 led to the phosphorus ylides RP-(CF 3 ) 2 CH 2 , stable in solution at ambient temperatu
