Abstract
4, 6-Phenanthroline 6-oxide (II), 4-oxide (IV), and 4, 6-dioxide (III) were synthesized from 4, 6-phenanthroline by various methods. The reaction of II, III, and IV with phosphoryl chloride gave some chlorinated compounds (V to IX), and the reaction of II with acetic anhydride gave 4, 6-phenanthrolin-5 (6H)-one (X) and 6-(5'-4', 6'-phenanthrolinyl)-4, 6-phenanthrolin-5 (6H)-one (XI). These results were compared with the same reaction of 1, 6-phenanthroline.
