  Electronic effects on the reactivity of copper mono-bipyridine complexes

  摘要：

  Electronic effects on the synthesis, structure and reactivity of copper 2,2'-bipyridine (bpy) complexes of formula [Cu(4,4'-R-2-2,2'-bipyridine)]Cl-2, where R = Cl, CH3, OCH3, and [Cu(4,4'-R-2-2,2'-bipyridine)](NO3)(2), where R = NO2, Cl, are reported. Pure complexes were formed, as shown by elemental analysis, for mono bpy Cu complexes when bpy ligands with groups R = Cl, CH3 or OCH3 were pre-dissolved in chloroform and added to methanol solution of CuCl2 in a 1: 1 molar ratio (compounds 1-3). Mono bpy Cu complexes were obtained when bpy ligands with groups R = Cl and NO2 were pre-dissolved in THF and added to methanol solution of Cu(NO3)(2) in a 1:1 molar ratio (compounds 4 and 5). Under the same conditions, for R = OCH3 the bis bipyridine complex [Cu(4,4'-(OCH3)(2)-2,2'-bipyridine)(2)(NO3)](NO3) (6) was formed. Suitable crystals of 4 and 6 center dot CH3OH for X-ray analysis were formed by the slow evaporation of solvent. The main electronic effect for the catalytic hydrolysis of methyl parathion by Cu(4,4'-R-2-2,2-bipyridine)(2+) ((aq)), where R = Cl, H and CH3, was a shift in the acid dissociation constant of coordinated water and a small increase in the second order rate constant, k(2), measured at pH 9.1.
