PPT 17.5 The Wittig and Related Reactions PowerPoint Presentation
Wittig Reagent Formation. Web formation of phosphonium salt. Wittig reagents are usually prepared from a phosphonium salt, which is in turn prepared by the quaternization of triphenylphosphine with an alkyl halide.
PPT 17.5 The Wittig and Related Reactions PowerPoint Presentation
Web 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. Web preparation of wittig reagents. The wittig reaction or wittig olefination is a chemical reaction. The ability of phosphorus to hold more than eight valence electrons allows for a resonance. Web for the wittig reaction discussed below an organophosphorus ylide, also called wittig reagents, will be used. Wittig reagents are usually prepared from a phosphonium salt, which is in turn prepared by the quaternization of triphenylphosphine with an alkyl halide. Wittig reagents are usually prepared from a phosphonium salt, which is in turn prepared by the reaction of triphenylphosphine with an alkyl halide via an s n 2 reaction.
