Preparation and characterization of a metal-containing ionic liquid DABCObasedLewis acid catalyst for the synthesis of quinoxalines

Quinoxalines are importan nitrogen containing heterocyclic compounds.this compounds canshow biological activities, medicinal and therapeutic properties, and also are used in variousfields such as paint industry, optoelectronics and agricultural chemistry.There are many methodsfor the synthesis of quinoxalines, but these methods have disadvantages, includingenvironmental hazards, which cannot be the optimal method for the synthesis of them.Thereforehere in we wish to report the use of a new DABCO based metal-containing ionic liquidas a Lewis acidic catalyst to achieve the desired compounds [۱,۲].This catalyst has unique properties such as high efficiency,short reaction time, easy workup,and the ability to bear a variety of functional groups wich brings economic as well asenvironmental rewords. (Scheme ۱).Scheme ۱: Synthesis of quinoxalines in the presence of DABCO-based metal-containing ionicliquid.
