2-(3-formylphenyl)imidazo[4,5-f][1,10]phenanthroline was prepared by a previously published method [1]. A mixture of 2-(3-formylphenyl)imidazo[4,5-f][1,10]phenanthroline (0.2 g, 0.62 mmol), acenaphthenequinone (0.124 g, 0.68 mmol), ammonium acetate (0.713 g, 9.3 mmol) and glacial acetic acid (10 cm3) was refluxed for about 3 h. The cooled solution was filtered and then poured into 100 cm3 ether. The crude product was collected and purified on alumina with ethanol-toluene (1:4 v/v) as eluent to give the title compound as
