A NEW METHOD FOR THE PREPARATION OF (2,2-DIPHENYLVINYLIDENE)-TRIPHENYLPHOSPHORANE AND ITS REACTION WITH CARBONYL COMPOUNDS

Hexaphenylcarbodiphosphorane (I), prepared from triphenylphosphine and carbon tetrahalide, when treated with benzophenone in equimolar ratio, gave the ylide (2,2-diphenylvinylidene)triphenylphosphorane (II) which, upon further treatment with benzophenone, gave 1,3-tetraphenylallene (III) via Witting reaction.
