A review of the role of hydrogen peroxide in organic transformations
Homa Targhan,Paul Evans,Kiumars Bahrami 한국공업화학회 2021 Journal of Industrial and Engineering Chemistry Vol.104 No.-
Under appropriate conditions, hydrogen peroxide is able to perform a multitude of oxidative organicreactions in an economically, technically, and environmentally satisfying manner. This review summarizesselected recent examples which feature the use of aqueous hydrogen peroxide in a various reactions. These serve to illustrate its value as an indispensable oxidising agent in organic synthesis.

Photocatalytic electron transfer reactions of aryl benzyl sulfides using 2,4,6 triphenylpyrilium tetrafluoroborate ($TP^+BF_4^-$) resulted in the oxidation of these sulfides to the corresponding sulfoxides and also in most cases in the C-S bond cleavage of them along with formation of aromatic aldehydes. In these reactions, the formation of sulfide radical cation has been proposed, which undergoes either oxidation to the corresponding sulfoxide or C-S bond cleavage to the formation of aromatic aldehydes. The further oxidation of sulfoxides to sulfones has not been observed. The influence of substrate structures on the reaction pathways as well as the role of $O_2$ in this respect is discussed.

Alpha and gamma-alumina are materials used as continuous coatings and also in variousfields such asceramics, catalysis and catalytic support, lubricants, and electronics. Boehmite (AlOOH) is used as the rawmaterial for the preparation of alpha and gamma-alumina phases whose properties such as morphology,specific surface area, and porosity, are strongly dependent on the boehmite structure. In this review,various methods for synthesizing boehmite nanoparticles (NPs); including, sol–gel, sedimentation,sewage, and hydrothermal have been reviewed. The most appropriate method for the production ofvarious forms of boehmite is the hydrothermal method. The shape, morphology, and tissue properties ofthe boehmite NPs depend heavily on the conditions of the process, i.e. the pH of the solution, thetemperature, and the reaction time which will be described in this review. Moreover, the application ofboehmite as the catalyst or catalytic support is studied in this review. Therefore, metallic, acidic, basic,ionic, organic, and organometallic catalysts, which are immobilized on boehmite NPs are discussed inthis review.
