Herein, we describe an efficient method involving the synthesis of diverse quinoxalines using the DMSO/ t BuONa/O 2 system as a single-electron oxidant to form α-imino radicals and nitrogen radicals for the direct construction of C-N bonds. This methodology provides a novel approach to form α-imino radicals with good reactivity.
