Nitric Acid → 2,9-Dimethyl-5-nitro-1,10-phenanthroline

Participants

Reaction Steps

Specifically, 2,9-dimethyl-1,10-phenanthroline shown by the formula (A) in FIG. 1 is reacted with an acid mixture composed of nitric acid and sulfuric acid to give 5-nitro-2,9-dimethyl-1,10-phenanthroline shown by the formula (B) in FIG. 1. The 5-nitro-2,9-dimethyl-1,10-phenanthroline is then reacted with selenium dioxide to give a dialdehyde compound shown by the formula (C) in FIG. 1. This dialdehyde compound is then oxidized to obtain the compound of the formula (1).
