- W1577354002 abstract "The preparation and synthetic applications of selenium‐ and tellurium‐stabilized carbanions as well as selenonium and telluronium ylides are reviewed. Selenium‐ and tellurium‐stabilized carbanions are prepared by deprotonation or by element/lithium exchange of the parent selenides and tellurides. Additionally, selenium‐stabilized carbanions are prepared by conjugate addition of organometallics to vinyl‐ and alkynyl selenides. Selenonium and telluronium ylides are prepared mainly by deprotonation of the parent selenonium and telluronium salts. The above‐mentioned anionic species react with electrophiles, giving intermediates, which by subsequent transformations, lead to synthetically useful products. In the case of the selenium‐stabilized carbanions, these sequences of reactions were applied in the synthesis of natural products. The tellurium counterparts were not yet explored for this purpose. Selenonium and telluronium ylides were not yet employed in total synthesis." @default.
