A facile and economic method for the fully regioselective and high-yielding protocol for the hydroamination of unsymmetrical internal alkynes under mild reaction conditions with AgNTf2 was developed. The materials are easily available from commercial vendors, to give synthetically useful enamine derivatives efficiently. This strategy is efficient to build complex structures from simple starting materials in an environmentally compatible fashion.

Herein, the intermolecularhydroamination of alkenes and alkynes with anilines catalyzed by HOTf under mild conditions has been developed. This reaction provides one of the simplest alkene and alkyne addition methods and is an alternative to metal-catalyzed reactions. At the same time, the intramolecular hydroamination of alkynes with anilines proceeds smoothly to obtain quinolines. We found that this
