  Thiol-yne click on nano-starch: An expedient approach for grafting of oxo-vanadium Schiff base catalyst and its use in the oxidation of alcohols

  摘要：

  The metal-free stoichiometric click reaction between thiol-functionalized nanocrystalline starch and yne-functional oxo-vanadium Schiff base has been demonstrated to be a simple, quantitative, mild and efficient approach for the development of heterogenized homogeneous complex via covalent bonding. The developed catalyst has found to be highly efficient and recyclable for the oxidation of various alcohols to corresponding carbonyl compounds with t-BuOOH under mild reaction conditions. Importantly, no leaching of metal or ligand is observed during the course of the reaction. (C) 2013 Elsevier B.V. All rights reserved.

  Multiple Oxo-Vanadium Schiff Base Containing Cyclotriphosphazene as a Robust Heterogeneous Catalyst for Regioselective Oxidation of Naphthols and Phenols to Quinones

  摘要：

  Grafting of multiple oxo-vanadium Schiff base moieties to cyclotriphosphazene provided an efficient and recyclable heterogeneous catalyst for the regioselective oxidation of naphthols and phenols to quinones by using t-butylhydroperoxide as oxidant. One of the main advantages of the developed catalyst was the presence of multiple oxo-vanadium moieties in close proximity which made the developed catalyst more active as compared to its homogeneous oxo-vanadium Schiff base. After the reaction, the catalyst was easily recovered from the reaction mixture by simple filtration and reused for five runs without loss in activity.

• Characterization of oxovanadium (IV)–Schiff-base complexes and those bound on resin, and their use in sulfide oxidation

  Oxovanadium (IV)-Schiff-base complexes and those bound on Merrifield resin as a polymer support were prepared for their characterization and their use as catalyst in oxidation of methyl phenyl sulfide. Schiff bases were prepared with use of salicylaldehyde and 2,4-dihydroxybenzaldehyde as the aldehydes and 2-aminoethanol, L-phenylalaninol, L-histidinol, and L-phenylalanine as the counterparts. Oxovanadium (IV) complexes made up of these Schiff bases and those bound on the resin were spectroscopically characterized. The polymer-supported Schiff-base complexes in the presence of tertiary-butylhydroperoxide converted the sulfide to the corresponding sulfoxide in 80-90% yield in CDCl3 in 90 min. They afforded slightly lower rates of oxidation than the corresponding monomeric complexes. They converted the sulfide in a stereoselective manner yielding the sulfoxide in enantiomeric excess (the highest value of 40%). The polymer-supported complexes and the corresponding monomers achieved almost the same enatiometric excesses with each other. (C) 2004 Elsevier B.V. All rights reserved.
