  Electron and energy-transfer reactions of with copper-phenolates

  摘要：

  Covalently-modified tyrosines are found as cofactors in enzymes such as galactose oxidase and the copper-dependent amine oxidases. In these cases, cofactor formation has been proposed to occur via oxidation of a copper-tyrosine precursor, making electron transfer chemistry in copper-phenolates a key to cofactor biogenesis. Our work was motivated by a desire to understand the ET reactivity of simple metal coordinated phenolate model complexes. Copper and zinc complexes of phenolate ligands were prepared, and their electron and energy-transfer reactivity toward Ru(R(2)bpy)(3)(2+)*(/3+) studied to test the electron-transfer reactivity of metal-coordinated phenolates. M(salxn) (M = Cu2+ Zn2+; salxn = salen, N,N'-disalicylidene-1,2-ethylenediamine; salpen, N,N'-disalicylidene-1,3-propylenediamine; salben, N,N'-disalicylidene-1,4-butylenediamine: salophen, N,N'-disalicylidene-o-phenylenediamine) were synthesized along with the more easily oxidized complexes Cu(bppa) (Hbppa, bis-pyridyl phenolamine) and Cu(icoph) (H(2)icoph, bis-iminocatechol o-phenylenediamine). Zn(salophen) and Cu(salophen) were oxidized by Ru(bpy)(3)(3+), indicating that electron transfer was thermodynamically favorable. Cu(salxn) complexes were observed to be efficient energy-transfer quenchers of Ru(bpy)(3)(2+)*; in contrast, Cu(bppa) and Cu(icoph) quenched Ru(bpy)3(2+)* by electron transfer, with observed reorganization energy lambda = 22 kcal/mol. The large self-exchange reorganization energy calculated for the Cu-coordinated phenolates suggest that the CAO and GalOx cofactors may be poor 1e(-) redox centers, with very slow rates for cofactor biogenesis.

  Bulky salen CuLx derived from aliphatic polymethylene diamines, H2N-(CH2)(x)-NH2, where n = 2-6, and 3,5-di-t-butylsalicylaldehyde (H2Lx) and some corresponding tetrahydrosalan complexes (CuL'(x)) have been synthesized and characterized by their IR, UV-vis absorption and EPR spectra, by magnetic moments and by cyclic voltammetry in acetonitrile (for H2Lx) and DMF (for CuLx). Complexes CuLx and CuL'(x) are magnetically normal (mu(exp) = 1.83-1.91 mu(B)). EPR spectra CuLx characterized by the axial g and A(Cu) tensors with g(parallel to) > g(perpendicular to) and without N-14-shf resolution in CHCl3/toluene at 300 and 150 K. The CV studies on acetonitrile solutions of H2Lx revealed a well-defined quasi-reversible redox wave at E-1/2 = 0.95-1.15 V versus Ag/AgCl but CV of the CuLx complexes in DMF exhibit weak pronounced irreversible oxidation waves at E-pa(1) = 0.51 - 0.98 V and E-pa(2) = 1.16 - 1.33 V attributable to metal centered Cu(II/III) and ligand centered CuLx/CuLx.+ couples, respectively. A poorly defined wave was observed for the quasi-reversible reduction Cu(II)/Cu(I) at potentials less than -1.0 V. (C) 2004 Elsevier B.V. All rights reserved.
