Abstract

An environmentally benign catalytic method for efficient synthesis of quinoxaline derivatives via the condensation reaction of 1,2-diamines and 1,2-dicarbonyl compounds using ZrOCl2.8H2O in EtOH as a standard green solvent under mild conditions has been developed. The reusability of the catalyst has been successfully examined without any noticeable loss of its catalytic activity.

Keywords: Quinoxaline, 1,2-diamines, 1,2-dicarbonyl compounds, ZrOCl2.8H2O, ethanol, EtOH, DPPZ, DPQ, DFQ, MnO2
