Reaction des oxirannes avec la triphenylphosphine en milieu phenolique

A new access to the vinylphosphonium salts 4 is proposed, using the reaction of epoxides 1 with triphenylphosphine at 100 deg C in phenol.It succeeds very well for the unfunctional epoxides 1 : 2-monosubstituted and 2,3-disubstituted epoxides.In the case of arylepoxides and 2,2-disubstituted unfunctional epoxides, Wittig and " retro-Wittig " side-reactions decrease the yields in vinylphosphonium salts.The reaction of opening epoxides by triphenylphosphine takes place since 40 deg C and is regio and stereoselective.At 40 deg C, the reaction leads to the formation of β-hydroxy alkylphosphonium salts 3.
