Aroyl Arenesulfonyl Peroxides. II. Phenylation with Phenyl Radical Generated from Benzoylp-Toluenesulfonyl Peroxide

Peroxides and Peroxide Forming Compounds

Inorganic and organic peroxides, because of their exceptional reactivity and oxidative potential are widely used in research laboratories. This review is intended to serve as a guide to the hazards and safety issues associated with the laboratory use, handling, and storage of inorganic and organic peroxy-compounds and peroxide-forming compounds. The relatively weak oxygen-oxygen linkage (bond-d...

Organic Peroxides in Radical Synthesis Reactions

Direct Oxidation of Aldehydes to Methyl Esters with Urea Hydrogen Peroxide and p-Toluenesulfonyl Chloride

Combination of urea hydrogen peroxide and p-toluenesulfonyl chloride in methanol was proved to be facile and highly efficient for the oxidative methyl esterification of various aldehydes to the corresponding carboxylic methyl esters.

Photochemical degradation of azure-b with sulphate radical ion generated by peroxydisulphate ion with cupric ion

In this paper, the photochemical degradation of azure-b by Cu2+/S2O82− process has beenpresented. Cu2+ as photocatalyst and S2O82− ion as photooxidant used in this process. Atextremely low concentrations, cupric ion showed true catalytic activity in the overall process.The influence of various parameters on the performance of the treatment process has beenconsidered, such as pH, concentration o...

Increase in microvascular permeability induced by enzymatically generated free radicals. II. Role of superoxide anion radical, hydrogen peroxide, and hydroxyl radical.

The roles played by superoxide anion radical (O,J, hydrogen peroxide, and hydroxyl radical (OH.) in the macromolecular permeability increase seen after addition of xanthine oxidase to the hamster cheek pouch has been studied. Fluorescein-labeled Dextran, l& 150,000 (FITC-Dextran 150) was used to assess microvascular permeability. Application of xanthine oxidase was associated with a marked incr...
