Treatment of 1,2-phenylenediamine with benzil analogs in the presence of a mixture of sodium bromate/sodium hydrogen sulfite in water gave the corresponding quinoxalines in high yields. The method is eco-friendly due to use of water instead of other hazar

A versatile synthetic route for the preparation of 2,3,6-trisubstituted quinoxalines in excellent yield is developed from θ-diamines and 1,2-dicarbonyl compounds in which aqueous hydrofluoric acid was employed as the medium and catalyst. Other salient features of this protocol include milder conditions, absence of coupling agents, and easy workup procedures.
