aziridinoquinoxalines using dual Ir(III)/Cu(I) catalysts under green light-emitting diode (LED) photolysis (λmax=525 nm), is described. The experimental and quantum chemical explorations suggest a triplet energy transfer mechanism followed by a ring-opening reaction ultimately leading to the formation of azomethine ylide intermediates that are trapped with copper(I) acetylides.
