Edge-Oxidation of Graphites by Hydrogen Peroxide
Langmuir, 2019A simple and eco-friendly procedure of edge oxidation of high-surface area graphites, based on hydrogen peroxide treatments at 60 °C, is presented. Already, short-term treatments lead to O/C weight ratios higher than 0.1, leaving unaltered interlayer spacing and correlation length.

Oxidation of Potato Starch by Hydrogen Peroxide
Starch - Stärke, 1995AbstractPotato starch was oxidized by hydrogen peroxide in alkaline and acidic reaction conditions with copper, iron and tungstate catalysts in order to introduce carboxyl and carbonyl groups to the starch molecule. Carbonyl contents up to 6.6 per 100 glucose units could be obtained, whereas carboxyl content remained low (up to 1.4).

[31] Oxidation with hydrogen peroxide
1972Publisher Summary Hydrogen peroxide is a relatively nonspecific oxidizing agent that reacts with a wide variety of organic compounds. The chemistry of the oxidation of proteins by this chemical has been extensively examined. It is found that under suitable, relatively mild conditions this reagent is highly specific for a small number of amino acid ...

Ascorbic Acid Oxidation by Hydrogen Peroxide
Analytical Biochemistry, 1998The oxidative degradation of ascorbic acid by hydrogen peroxide was examined to determine routes of degradation and identify the initial products which form when ascorbic acid is oxidized. When reacted with hydrogen peroxide, solutions of ascorbic acid and dehydroascorbic acid are both ultimately oxidized to the same species, having a mass spectrum ...

Triphenylarsine oxide–hydrogen peroxide adduct
J. Chem. Soc. A, 1968Triphenylarsine reacts with hydrogen peroxide to give a crystalline substance whose composition is Ph3AsO,H2O2. The structure of the material and of the corresponding phosphine oxide complex is discussed.

Asymmetric Epoxidation Using Hydrogen Peroxide as Oxidant
Chemistry – An Asian Journal, 2015AbstractAsymmetric epoxidation is one of the most important transformations in organic synthesis. Although tremendous progress was achieved in this field in the 1980s and 1990s, it is still desirable from both economical and ecological views to develop environmentally friendly catalytic epoxidation with a broad substrate scope.

Oxidation of Good’s buffers by hydrogen peroxide
Analytical Biochemistry, 2006Good's zwitterionic buffers are widely used in biological and biochemical research in which hydrogen peroxide is a solution component. This study was undertaken to determine whether Good's buffers exhibit reactivity toward H(2)O(2). It is found that H(2)O(2) oxidizes both morpholine ring-containing buffers (e.g., Mops, Mes) and piperazine ring ...

Oxidative Halogenation with “Green” Oxidants: Oxygen and Hydrogen Peroxide
Angewandte Chemie International Edition, 2009AbstractIt is difficult to imagine organic chemistry without organo‐halogen compounds and the molecular halogens needed for their preparation. The halogens have very different reactivity, with iodine usually requiring some form of activation, while others are reactive and hazardous chemicals.

On pyrrole oxidation with hydrogen peroxide
Tetrahedron, 1970Abstract A qualitative study of the influence of the reaction medium on pyrrole oxidation with hydrogen peroxide is reported. In neutral aqueous solution a good yield of a simple oxidation product was obtained of which the isolation, structure, and some aspects of the chemical reactivity are reported.

Baeyer–Villiger Oxidation Using Hydrogen Peroxide
ACS Catalysis, 2013The Baeyer–Villiger (BV) oxidation of carbonyl compounds to the corresponding esters or lactones is one of the most important transformations. We recently introduced a highly efficient and selective LiB(C6F5)4- or Ca[B(C6F5)4]2-catalyzed BV oxidation of ketones with aqueous hydrogen peroxide to give the corresponding lactones in high yield.
