Copper-catalyzed carboarylation of alkynes via vinyl cations

Walkinshaw, Andrew J.,Xu, Wenshu,Suero, Marcos G.,Gaunt, Matthew J.

, p. 12532 - 12535 (2013/09/23)

Copper-catalyzed arylation of electron rich alkynes reveals stabilized trisubstituted vinyl cation equivalents that react with pendant arene nucleophiles to form all carbon tetrasubstituted alkenes. The new process streamlines the synthesis of important medicinally relevant molecules.
