Definition of Ylides. Meaning of Ylides. Synonyms of Ylides

- ions like palladium and platinum. Other common ylides include sulfonium ylides and sulfoxonium ylides; for instance, the Corey-Chaykovsky reagent used...
- groups can be present if conjugated with the ylide — these are the stabilised ylides mentioned above. Bis-ylides (containing two P=C bonds) have also been...
- azomethine ylides has verified that cycloaddition is also stereospecific with respect to the dipole component. Diastereopure azomethine ylides are generated...
- stereocenters. Azomethine ylides thus have high utility in total synthesis, and formation of chiral ligands and pharmaceuticals. Azomethine ylides can be generated...
- diverse. The reaction has come to encomp**** reactions of many types of sulfur ylides with electrophiles well beyond the original publications. It has seen use...
- Nitrile ylides also known as nitrilium ylides or nitrilium methylides, are generally reactive intermediates formally consisting of a carbanion of an alkyl...
- an important step when optimizing a Wittig reaction. Because phosphonium ylides are seldom isolated, the byproduct(s) generated upon deprotonation essentially...
- William D. Emmons further defined the reaction. In contrast to phosphonium ylides used in the Wittig reaction, phosphonate-stabilized carbanions are more...
- particular example of the well-known 1,3-dipolar cycloaddition of azomethine ylides to olefins. In fullerene chemistry this reaction refers to the functionalization...
- sulfonium and oxosulfonium salts affords ylides, of structure R2S+−C−−R′2 and R2S(O)+−C−−R′2. While sulfonium ylides, for instance in the Johnson–Corey–Chaykovsky...
