New DNA Intercalating Acridinic Ligands: Comparative Copper-Catalyzed N-Arylation Reactions of 4-Aminoacridine with Organobismuth, Organoboron and Organolead Compounds

Copper diacetate catalyzed phenylation of 4-aminoacridine afforded the N-phenyl derivative in good yields with triphenylbismuth diacetate, moderate yields with phenylboronic acid and failed with in situ generated phenyllead triacetate. All systems gave high yields of the N-monophenyl derivative in their reaction with 3,4-dimethylaniline.
