- Аннотация: The catalytic behavior of binuclear chelates of Cu(II) based on phenylhydrazoneimines originated from 3-amino-1-propanol, beta-alanine, and anthranyl acid was studied in the model reaction of liquid-phase cyclohexene oxidation by molecular oxygen. Square-planar binuclear chelates of Cu(II) have a stable configuration and are distinguished by a higher catalytic activity, compared to mononuclear square-planar analogs. The catalytic activity of binuclear chelates depends both on the electron donor-acceptor properties of the substituent at the gamma-position of the quasiaromatic metal containing cycle and on the chemical nature of imine fragments of the ligand. A higher catalytic activity of binuclear Cu(II) chelates based on phenylhydrazoneimines in comparison to their mononuclear analogs is caused by the non-equivalency of Cu-O bonds: the rupture of one of these bonds results in a coordinatively unsaturated monomer.
