  Copper-mediated oxygenation of flavonolate in the presence of a tridentate N-ligand. Synthesis and crystal structures of [Cu(fla)(idpaH)]ClO4 and [Cu(idpaH)(O-bs)]ClO4, [fla=flavonolate, idpaH=3,3′-iminobis(N,N-dimethylpropylamine), O-bs=O-benzoylsalicylate]

  摘要：

  The complexes [Cu(fla)(idpaH)] ClO4 (4) and [Cu(idpaH)(O-bs)] ClO4 (5) (fla = flavonolate, idpaH = 3,3'-iminobis(N, N-dimethylpropylamine), O-bs = O-benzoylsalicylate) have been synthesised and characterised. Complex 5 can be obtained also by the oxygenation of 4 and concomitant CO release. The structures of the compounds have been determined by X-ray diffraction. Complex 4 exhibits distorted trigonal-bipyramidal geometry around the copper(II) ion while complex 5 is distorted square-pyramidal. (C) 2000 Elsevier Science S.A. All rights reserved.

  The oxygenolytic cleavage of flavonolate coordinated to copper(II) with the auxiliary ligand 3,3'-iminobis(N,N-dimethyl-propylamine), [Cu-II(fla)(idpa)]ClO4, is enhanced by the addition of acetate and benzoate. Monodentate coordination of the flavonolate forced by the carboxylate ligands is believed to be the reason for the higher reaction rates. (C) 2003 Elsevier B.V. All rights reserved.

  Oxygenation of [Cu-II(fla)(idpa)]ClO4 (fla = flavonolate; idpa = 3,3'-iminobis(N,N-dimethylpropylamine)) in dimethylformamide gives [Cu-II(idpa)(O-bs)]ClO4 (O-bs = O-benzoylsalicylate) and CO. The oxygenolysis of [Cu-II(fla)(idpa)]ClO4 in DMF was followed by electronic spectroscopy and the rate law - d[Cu-II(fla)(idpa)}ClO4]/dt = k(obs)[Cu-II(fla)(idpa)}ClO4][O-2] was obtained. The rate constant, activation enthalpy and entropy at 373 K are k(obs) = 6.13 +/- 0.16 x 10(-3) M-1 s(-1), DeltaH(double dagger) = 64 +/- 5 kJ mol(-1), DeltaS(double dagger) = -120 +/- 13 J mol(-1) K-1, respectively. The reaction fits a Hammett linear free energy relationship and a higher electron density on copper gives faster oxygenation rates. The complex [Cu-II(fla)(idpa)]ClO4 has also been found to be a selective catalyst for the oxygenation of flavonol to the corresponding O-benzoylsalicylic acid and CO. The kinetics of the oxygenolysis in DMF was followed by electronic spectroscopy and the following rate law was obtained: -d[flaH]/dt = k(obs)[Cu-II(fla)(idpa)}ClO4][O-2]. The rate constant, activation enthalpy and entropy at 403 K are k(obs) = 4.22 +/- 0.15 x 10(-2) M-1 s(-1), DeltaH(double dagger) = 71 +/- 6 kJ mol(-1), DeltaS double dagger = -97 +/- 15 J mol(-1) K-1, respectively.
