S,C-Sulfonium Ylides from Thiophenes: Potential Carbene PrecursorsThe Journal of the American Chemical Society
Publication VersionPublished Version
AbstractPhotolysis of S,C-sulfonium ylides derived from thioanisol, thiophene, benzothiophene, or dibenzothiophene provides products deriving from dicarbomethoxycarbene. In methanol, no rearrangement of the carbene to the ketene derivative is observed. Formation of dibenzothiophene and benzothiophene is quantitative. For the thiophene-based ylide, insertion of the carbene into the α-CH bond of thiophene is observed. Evidence is presented that supports formation of both singlet and triplet carbene.
