A facile, copper-catalyzed aminoarylation reaction of various aryl/alkyl alkynes was realized by utilizing N-fluoroarylsulfonimides (NFSI) as aminoarylation or amination reagent with hydroxyl as directing group. With this methodology, various α,β-unsaturated carbonyl compounds and indenones were efficiently constructed, and the synthetic application for indole derivatives was also provided. The aminoarylation
