Studies on the Reactions of Heterocyclic Compounds. II. Syntheses and Some Reactions of 1, 6-Phenanthroline N-Oxides

Abstract

1, 6-Phenanthroline was synthesized from 4-aminoquinoline by the Skraup reaction using sulfo-mix, and N-oxidation was carried out in various ways to obtain 6-oxide and 1, 6-dioxide. Reactions of 6-oxide with acetic anhydride and with phosphoryl chloride and the Reissert reaction were carreid out and the results were compared with those in the case of 1, 6-naphthyridine.
