Electricity-driven, Oxidative C-H Selenylative and Tellurylative Annulation of -(2-alkynyl)anilines: Sustainable Synthesis of 3-selanyl/tellanylquinolines

A metal- and oxidant-free, radical C-H selenylative and tellurylative annulation of -(2-alkynyl)anilines with diorganyl dichalcogenides is developed under electrochemical conditions for the sustainable synthesis of valuable 3-selanyl/tellanylquinolines up to 92% yield at room temperature. The developed protocol required only electricity as the green reagent and offers high atom economy, broad substrate scope, and efficient scalability.
