Wittig reaction - Wikipedia
The Wittig reaction or Wittig olefination is a chemical reaction of an aldehyde or ketone with a triphenyl phosphonium ylide called a Wittig reagent. Wittig reactions are most commonly used to convert aldehydes and ketones to alkenes.
The Wittig Reaction - Chemistry LibreTexts
2023年1月23日 · Organophosphorus 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.
Wittig Reaction - Organic Chemistry Portal
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.
Wittig Reaction: Mechanism, Applications, Limitations - Science Info
2023年8月27日 · Wittig reaction facilitates the formation of an alkene by reacting an aldehyde or ketone with the ylide produced by a phosphonium salt. The reactivity of the ylide affects the geometry of the resultant alkene.
Wittig Reaction - an overview | ScienceDirect Topics
The Wittig reaction is the chemical reaction of an aldehyde or ketone with a triphenyl phosphonium ylide (the Wittig reagent) to afford an alkene and triphenylphosphine oxide. Noteworthy, this reaction results in the synthesis of alkenes in a selective and predictable fashion.
Wittig Reaction Mechanism with Reagent Preparation - BYJU'S
Wittig reaction is an organic chemical reaction wherein an aldehyde or a ketone is reacted with a Wittig Reagent (a triphenyl phosphonium ylide) to yield an alkene along with triphenylphosphine oxide. This Reaction is named after its discoverer, the German chemist Georg Wittig.
The Wittig Reaction: Examples and Mechanism - Chemistry Steps
The 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 Mechanism and Applications - Chemistry Notes
Wittig reaction involves the reaction of aldehydes or ketones (aliphatic or aromatic) with wittig reagents to produce olefin. Triphenylphosphinealkylidenes or alkylidenephosphoranes are widely used as wittig reagents.
Wittig Reaction - Mechanism, Preparation, Examples, Significance …
Wittig reaction is a chemical reaction in which a carbonyl compound (aldehyde or ketone) reacts with a triphenyl phosphonium ylide to give an alkene. Thus, it is a useful reaction to convert aldehydes or ketones into alkenes.
