Mild and Efficient Oxidation of Alcohols with NaIO4 Catalyzed by a Manganese Porphyrin-polyoxometalate Hybrid Material
Efficient and selective oxidation of alcohols with NaIO4 catalyzed by an organic-inorganic hybrid material in which manganese(III)5,10,15,20-tetrakis(4-aminophenyl)porphyrin chloride, MnIII(TAPP)Cl, is covalently linked to a Lindqvist structure of polyoxometalate, Mo6O192-, at room temperature is reported. The effect of various parameters such as catalyst amount, solvent and oxidant were studie...
متن کاملO-Xylylenebis (Triphenylphosphonium) Dibromochromate: A Selective and Efficient Reagent for Oxidation of Alcohols, Trimethylsilyl Ethers and Thiols
Alcohols, trimethylsilyl ethers and thiols were efficiently converted to their corresponding carbonyl and disulfides compounds using o-xylylenebis (triphenylphosphonium) dibromochromate (XTPPDBC). This reagent can selectively oxidize thiols to disulfides in the presence of alcohols and trimethylsilyl ethers in acetonitrile at room temperature.
متن کاملSynthesis and reactions of N-methylbenzylammonium fluorochromate(VI) on silica gel, a selective and efficient heterogeneous oxidant.
N-Methylbenzylammonium fluorochromate(VI) (MBAFC) is easily synthesized by addition of N-methylbenzylamine to an aqueous solution of CrO3 and HF. MBAFC shows selectivity in the oxidation of aryl alcohols to their corresponding aldehydes and ketones under mild conditions. The durability, ease of work up and efficiency of MBAFC are considerably increased upon its absorption on silica gel.
متن کاملVanadium oxide supported on mesocellulous silica foams (MCF): An efficient and reusable catalyst for selective oxidation of sulfides
A green, efficient and selective approach for the oxidation of sulfides to sulfoxides and sulfones with UHP at room temperature is reported. The reaction is performed in the presence of vanadia catalyst supported on mesocellular silica foam (MCF) with a V content ranging from 2% to 10% as heterogeneous and reusable catalyst. The structural and textural characterization of this catalyst were don...
متن کاملSynthesis, Characterization and Catalytic Performance in the Selective Oxidation of Alcohols by Metallophthalocyanines Supported on Zinc Oxide Nanoparticles
Unsubstituted phthalocyanines of Co, Fe and Mn supported on zinc oxide nanoparticles were prepared and were well characterized with X-ray diffraction and scanning electron microscopy. The oxidation of alcohols with tert-butylhydroperoxide, in the presence of metallophthalocyanines supported on zinc oxide nanoparticles was investigated. These MPc/ZnO nanocomposites were effective catalysts for t...
