ChemInform Abstract: Synthesis of Quinolyl-Substituted 4,7-Phenanthrolines

1-(2-Quinolyl)-3-aryl-4,7-phenanthrolines were synthesized by reacting arylidene-6-quinolylamines with 2-acetylqidnoline in n-butanol in the presence of hydrochloric acid. It was found that the formation of the 4,7-phenanthroline ring is preceded by the stage of formation of an intermediate aminoketone, 1-(2-quinolyl)-3-phenyl-3-(6-quinolylamino)propan-1-one. The IR, UV, PMR, and mass spectra of the synthesized compounds are discussed.
