The Wittig Reaction allows the preparation of an alkene by the reaction of an aldehyde or ketone with the ylide generated from a phosphonium salt. The geometry of the resulting alkene depends on the reactivity of the ylide. If R is an electron withdrawing group, then the ylide is stabilized and is not as reactive as when R is alkyl.
Stabilized ylides give predominantly E -alkenes whereas non-stabilized ylides lead to Z -alkenes see also Wittig-Horner Reaction.
Writing from life download free pdf wittig posultated mechanisms lead first to a betaine as a zwitterionic intermediate, which would then close to the oxaphosphetane. The intermediacy of such betaines plays an important role in the Schlosser Modification. Reactive ylides give rapid reaction and subsequent rapid ring opening to give the Z -alkene:.
