- The Wittig Reaction - Chemistry LibreTextsOrganophosphorus ylides react with aldehydes or ketones to give substituted alkenes in a transformation called the Wittig reaction. This reaction is named for George Wittig who was awarded the Nobel prize for this work in 1979.
- The Wittig Reaction: Examples and Mechanism - Chemistry StepsThe Wittig reaction is used for converting a carbonyl group to an alkene. Learn about the mechanism of Witting reaction and examples of its application.
- Wittig Reaction - Organic Chemistry PortalThe 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.
- Stereoselective Olefination Reactions: The Wittig ReactionWittig, G.; Geissler G. Liebigs Ann. 1953, 580, 44-57. Phosphonium ylides react with aldehydes to produce oxaphosphetane 1Z or 1E, which decomposes by a syn-cycloreversion process to the alkene. In the formation of Z-alkenes, an early, four-centered transition state is proposed.
