    Effective Oxidation of Alcohols with H5IO6Catalyzed by Nickel(II) Schiff Base Complexes
    摘要:
    Nickel(II)-Schiff base-triphenylphosphine complexes catalyze oxidation of alcohols to carbonyls in presence of minimum amount of periodic acid. The catalytic oxidation was developed in mild conditions and showed good yields. The effects of temperature, time, and concentrations of catalyst and co-oxidant were studied. Higher catalytic activity has been observed for NiL1 compared to the other complexes.

    Abstract A coordination complex system consisting of Cobalt (II)-Schiff bases with triphenylphosphine were synthesized and characterized. These catalysts were effective in the oxidation of primary and secondary alcohols. The oxidation reactions were carried out in ethyl-methyl-imidazolium ionic liquid in presence of NaOCl. Higher catalytic activity was observed for CoL1.

    structures of two representative complexes have been determined by X-ray crystallography. In each structure, the metal centre is in a distorted octahedral N2O4 coordination sphere. The tridentate phsalR− coordinates the metal ion via the pyridine-N, the imine-N and the phenolate-O atoms in a meridional fashion. The remaining three coordinations sites are occupied by the bidentate O,O-donor acetylacetonate
