DIRECT SYNTHESIS AND PROPERTIES OF BINUCLEAR COPPER(II) COMPLEXES
摘要:
At room temperature, dibenzoyl peroxide undergoes an oxidative addition reaction with metallic copper powder and the relevant ligands afford binuclear copper(Il) complexes, [CU(OOCC6H5)(2)L](2), L=pyridine-2,6-dicarboxylic acid (L-1), THF (L-2), 3-aminopyridine (L-3), 4-aminopyridine (L-4), 2-methylpyridine (L-5), 2,6-dimethylpyridine (L-6) and 2-aminothiazol (L-7). These complexes were further characterized by physico-chemical and spectroscopic methods. The structure of complex (7) has been determined by a single-crystal X-ray analysis. Each copper(II) ion is coordinated by two bridging bidentate benzoates and one L (as defined above) ligand to form dimeric binuclear molecules.
