A transition metal-free synthesis of 2-arylquinoxaline is achieved by using arylhydrazine salt as an aryl radical arylation reagent and air as an oxidant in the presence of K2CO3. This protocol features metal-free, no additives, mild reaction conditions, environment friendly, and can be used to construct biologically active molecules containing 2-phenylquinoxaline structure.
