Boric acid (BO3H3) catalyzed three component improved procedure for the synthesis of various 2–Phenylimidazo [4, 5-f] [1, 10] phenanthrolines from 1, 10- phenanthroline-5, 6-dione, aromatic aldehydes and ammonium acetate at roomtemperature in excellent isolated yield has been reported. This is a simple and straight forward, high yielding, does not involve any hazardous or expensive catalyst. The synthesis is purely solvent free.
