Characteristics of Polyaniline Cobalt Supported Catalysts for Epoxidation Reactions

A study of polyaniline (PANI) doping with various cobalt compounds, that is, cobalt(II) chloride, cobalt(II) acetate, and cobalt(II) salen, is presented. The catalysts were prepared by depositing cobalt compounds onto the polymer surface. PANI powders containing cobalt ions were obtained by one- or two-step method suspending PANI in the following acetonitrile/acetic acid solution or acetonitril...

Novel Polyaniline Supported Cobalt Catalyzed Aerobic Oxidation of Alkenes

Efficient soluble polymer-supported sharpless alkene epoxidation catalysts.

High chemical yields and good enantiomeric excesses are obtained by using soluble polymer-supported tartrate ester in the epoxidation of trans-hex-2-en-1-ol using Ti(OPri)4/tert-butyl hydroperoxide.

Self-supported chiral catalysts for heterogeneous enantioselective reactions.

The development of heterogeneous chiral catalysts for enantioselective reactions is highly desirable in order to overcome some drawbacks of homogeneous catalysts. Different from the conventional approaches by using various types of supports or biphasic systems for the recovery and reuse of homogeneous catalysts, a conceptually new strategy for heterogenization of homogeneous chiral catalysts, t...

Study on spinel supported gold catalysts for alcohol oxidation reactions

Gold had been regarded as an inactive metal in catalysis due to its inert chemical nature. However, it was found that when gold is prepared as nanoparticles, it can exhibit surprisingly high activity for various reactions, especially for oxidation reactions [1]. In order to obtain gold nanoparticles (AuNPs), support is commonly used, which can not only help to avoid agglomeration of AuNPs, but ...
