SYNTHESIS,CHARACTERIZATION, AND CATALYTIC OXIDATION PROPERTIES OF POLYMER-BOUND NICKEL COMPLEXES

Polystyrene-bound-2,2′-bipyridine-nickel-L (where L = 2,2′-bi-pyridine, oxine and 1,10-phenanthroline) complexes were synthesized and characterized by IR, X-ray photoelectron spectroscopy, TG-DTA, ICP and routine elemental analysis. The complexes have been shown to catalytically oxidize cyclohexene in the presence of molecular oxygen and in the absence of solvent at 70°C, without the use of any special oxidant or coreductant. When cyclohexene is oxidized, 2-cyclohexen-1-ol, 2-cyclohex-en-1-one and 2-oxygen-heterodicyclo4.1.0]heptane were produced.
