Polyethylene glycol (PEG-400) mediated synthesis of quinoxalines Nagarapu, Lingaiah Mallepalli, Raghu Arava, Glory Yeramanchi, Lingappa α-Halo ketones o-Phenylenediamines Quinoxalines Catalyst-free Polyethylene glycol PEG-400 A simple and highly efficient protocol for the synthesis of quinoxaline derivatives from various ortho-phenylenediamines with α-halo ketones under catalyst free conditions is reported by using polyethylene glycol (PEG-400) as an efficient recyclable medium without using any organic co-solvent or additive. This protocol gives wide range of quinoxaline derivatives with high yields.
