An efficient and one pot method for smooth conversion of substituted aldehydes and 1,10,phenanthroline-5-dione into 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 ionic liquid as a catalyst as well as solvent . The ionic liquid can be recycled and reused several times. 2-phenylimidazo [4,5-f] [1,10]-phenanthroline was synthesized and tested for antibacterial effects against Bacillus Subtilis, Escherichia coli, Staphylococcus aureus and Pseudomonas aeruginosa. The antibacterial screening of the synthesized compounds were performed in vitro by the filter paper disc diffusion method. The short reaction time, clean reaction, and easy workup make this protocol green and practically economical attractive and efficient.
