Synthesis, structures, electrochemistry and catalytic activities of copper(II) and palladium(II) complexes with asymmetric tetraazacycloannulenes

The copper(II) and palladium(II) complexes with 15-membered asymmetric 5,9-dihydro-2,4,10,12-tetramethyl-1,5,9,13-monobenzotetraazacyclo[15]tetradecine have been synthesized and characterized by electrochemical behavior and catalytic activities. The structures of the 15-membered copper(II) and palladium(II) complexes were determined using the X-ray diffraction method.
