Three new neutral complexes of copper(II) containing chalcone ligands derived from 2'-
hydoxyacetophenone and 4-substituted benzaldehydes were synthesized. Complexes were prepared
by solution synthesis and characterized by spectroscopy. The catalytic activity of complexes was
examined in the reaction of 3,5-di-test-butyl catechol (DTBC) oxidation. The kinetics of DTBC
catalytic oxidation by copper(II) complexes (1–3) was investigated spectrophotometrically under
pseudo-first-order conditions. Catalytic parameters, the maximum reaction rate (vmax), Michaelis-
Menten constant (KM), catalytic efficiency, catalytic reaction rate constant (kcat), turnover number
(TON), and turnover frequencies (TOF) for complexes 1–3 in DTBC oxidation were collected. The
studied complexes 1 and 2 were found to have moderate catalytic activity, while complex 3 does not
show catalytic properties.
