Kinetics and mechanism of the stoichiometric oxygenation of the ionic zinc(II) flavonolate complex [Zn(fla)(idpa)]ClO4 (fla = flavonolate; idpa = 3,3′-iminobis(N,N-dimethylpropylamine))

The preparation and characterization of [ZnII(4′R-fla)(idpa)]ClO4 (fla = flavonolate; idpa = 3,3′-iminobis(N,N-dimethylpropylamine) complexes were described. Oxygenation of ZnII(fla)(idpa)]ClO4 in dimethylformamide (DMF) solution at elevated conditions gave ZnII(idpa)(O-bs)]ClO4 (O-bs = O-benzoylsalicylate) and CO. The oxygenolysis of [ZnII(fla)(idpa)]ClO4 in DMF was followed by electronic spectroscopy and the rate constants were determined according to the rate law -d[{ZnII(fla)(idpa)}]ClO4]/dt = kobs [{ZnII(fla)(idpa)}ClO4][O2]. The rate constant, activation enthalpy and entropy at 373 K were kobs/M-sec =(3.11 ± 0.12) × 10-3, ΔH (kJ/mol) = 75 ± 5, @Delta;S (J/mol-K) = -96 ± 13. The reaction fitted a Hammett linear free energy relationship for 4′-substituted flavonols, and electron-releasing groups made the oxygenation reaction faster. In the course of the reaction O2·- was formed suggesting a SET mechanism. [ZnII(fla)(idpa)]ClO4 did not catalyze the oxygenation of flavonols.
