Abstract

Palladium-catalyzed amination of 2-chloro-1-azaazulene with 2-aminopyridine was studied under various conditions in order to obtain N-(1-azaazulen-2-yl)-N-(2-pyridyl)amine (4) and N,N-bis(1-azaazulen-2-yl)-N-(2-pyridyl)amine (5) as a multidentate ligand. Results of the reaction and physical and chemical properties of 4 and 5 are described.
