gold sulfide oxidation with hydrogen peroxide

hydrogen peroxide - organic-chemistry.org

hydrogen peroxide in the presence of zirconium tetrachloride is a very efficient reagent for the direct oxidative conversion of thiols and disulfides into the corresponding sulfonyl chlorides with high purity through oxidative chlorination.

oxidation with peroxides

oxidation with hydrogen peroxide and t butyl hydroperoxide hydrogen peroxide is a general purpose oxidant. the inherent reactivity is not very high so it is commonly used with acid base or transition metal catalysts which provide more aggressive nucleophilic or eletrophilic oxidants.

hydrogen peroxide is a powerful oxidizer usp technologies

hydrogen peroxide is a powerful oxidizer . hydrogen peroxide advantages . h2o2 is powerful. hydrogen peroxide is one of the most powerful oxidizers known -- stronger than chlorine chlorine dioxide and potassium permanganate. and through catalysis h2o2 can be converted into hydroxyl radicals (.oh) with reactivity second only to fluorine.

hydrogen peroxide - wikipedia

hydrogen peroxide is both an oxidizing agent and reducing agent. the oxidation of hydrogen peroxide by sodium hypochlorite yields singlet oxygen. the net reaction of a ferric ion with hydrogen peroxide is a ferrous ion and oxygen. this proceeds via single electron oxidation and hydroxyl radicals.

dakin oxidation - wikipedia

the dakin oxidation (or dakin reaction) is an organic redox reaction in which an ortho- or para-hydroxylated phenyl aldehyde (2-hydroxybenzaldehyde or 4-hydroxybenzaldehyde) or ketone reacts with hydrogen peroxide in base to form a benzenediol and a carboxylate. overall the carbonyl group is oxidized and the hydrogen peroxide is reduced.
