A new copper-catalyzed trifluoromethylarylation reaction of alkynes has been developed. The transformation represents the first example of endo-type carbotrifluoromethylation of unsaturated carbon-carbon bonds and provides efficientaccess to a variety of CF3-substituted dihydronaphthalenes and chromenes.

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