Carbon-nitrogen bond-forming reactions of palladacycles with hypervalent iodine reagents

Palladium(II) complexes containing bidentate cyclometalated C similar to N chelating ligands are shown to react with PhINTs at room temperature to insert NTs into the Pd-C bond. This NTs insertion reaction has been applied to palladacyclic complexes of azobenzene, benzo[h]quinoline, and 8-ethylquinoline. The newly aminated organic ligands can be liberated from the metal center by protonolysis with trifluoroacetic acid or HCl.
