SiO₂-FeCl₃ Mediated a Simple and Efficient Procedure for the Synthesis of Quinoxalines at Room Temperature

Silicasupported FeCl₃ (SiO₂-FeCl₃) has been used as an efficient catalyst for rapid synthesis of quinoxalines at room temperature. Quinoxalines derivatives were synthesized from 1, 2-diamine and 1, 2-dicarbonyl compounds by one pot condensation using SiO₂-FeCl₃ in ethanol at room temperature. This protocol is simple, efficient and gives good to excellent yield. The synthesized compounds were characterized by IR, 1H-NMR and mass spectroscopic analysis method.
