摘要：
Synthesis of quinoxalines from o-phenylenediamines (o-PDs) with electronically diversified 1,2-diketones and alpha-bromoketones via simple cyclocondensation reaction using an heterogeneous nano-Y-Fe2O3-SO3H catalyst has been reported under solvent free condition. Low cost, easy workup, high yield, operational simplicity, less reaction time, environmentally benign nature and catalyst is magnetically retrievable and can be reused up to five catalytic cycles without significant loss in the product yields are the noteworthy features of this protocol.
