IONIC LIQUID ASSISTED GREEN SYNTHESIS OF 2-PHENYLIMIDIZO [4,5-F][1,10]- PHENANATHROLINE AT ROOM TEMPERATURE

Abstract

A range of 2-phenylimidazo [4,5-f] [1,10]-phenanthroline have been synthesized in very good yield under solvent-free conditions by grinding 1,10,phenanthroline-5dione,aromatic aldehydes and ammonium acetate in the presence of [HBim]BF4 as catalyst. The short reaction time, clean reaction, and easy workup make this protocol practically economical attractive and efficient.
