In situ one-pot template synthesis (IOPTS) and characterization of copper(II) complexes of 14-membered hexaaza macrocyclic ligand “3,10-dialkyl-dibenzo-1,3,5,8,10,12-hexaazacyclotetradecane”

Abstract

A new copper(II) complexes of 14-membered hexaaza macrocyclic ligands; 3,10-dialkyl-dibenzo-1,3,5,8,10,12-hexaazacyclotetradecane, [Cu(R 2Bzo 2[14]aneN 6)] 2+ (R = H, Me, Et, Bu, Benzyl); have been prepared by the in situ one-pot template synthesis (IOPTS) of formaldehyde and 1,2-phenylenediamine with alkyl or benzyl amine in the presence of copper(II) ion. The complexes of a hexaaza macrocycle have been characterized by elemental analyses, IR, FAB, UV–Vis, and H NMR spectroscopy, conductometric and magnetic measurements.
