Ethinylphosphonium salts 4 react with methylenetriphenylphosphorane 5 to give 1.3-bis(triphenylphosphonio)propenid-cation salts 6, whereas from 4 with benzylidenetriphenylphosphorane 10α and isopropylidenetriphenylphosphorane 10β the 1.3-diphosphaallyl-cation salts 13 are formed in a stereospecific reaction.
