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.

2018年2月6日 · The Wittig Reaction converts aldehydes and ketones into alkenes through reaction with a phosphorus ylide. Mechanism and examples below.

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.

2023年1月23日 · The Wittig reaction is a chemical reaction of an aldehyde or ketone with a triphenyl phosphonium ylide (often called a Wittig reagent) to give an alkene and triphenylphosphine oxide.

The Wittig Reaction is an Olefination Reaction where a Phosphonium Ylide (Wittig Reagent) Reacts with a Ketone or Aldehyde via an Oxaphosphetane.

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.

The Wittig reaction or Wittig olefination is a chemical reaction of an aldehyde or ketone with a triphenyl phosphonium ylide (often called a Wittig reagent) to give an alkene and triphenylphosphine oxide.

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.

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.

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.
