An enthalpically favored H-atom abstraction from the benzylic site followed by a single electron transfer (SET) step to produce a benzylic carbocation was speculated as a plausible mechanism by us for the selective oxidation at the benzylic carbon. In this study, we demonstrate the capture of ...
• Benzylic carbons (w/at least one H) can be oxidized to carboxylic acids with KMnO 4. Some of the oxidative steps are straight oxidations, and some are oxidative cleavage reactions, depending on the substitution of the benzylic carbon. ...
How can a benzylic radical possibly be generated when the benzylic carbon has three alkyl groups attached? It can’t – and the reaction fails. 8. Applications of Benzylic Bromination So why might benzylic bromination be useful? Well, it allows us to employ all the reactions of alkyl hal...
Direct oxidation of KA oil (the mixture of cyclohexanone and cyclohexanol) toward ε-caprolactone is in high demand yet hard to implement in need of juggling the activation of both methyne C-H bond of cyclohexanol and α-C-C bond of cyclohexanone. Here w
Rhenium-catalyzed alpha-alkylation of enol acetates with alcohols or ethers When benzylic and allylic alcohols were treated with enol acetate in the presence of a catalytic amount of a rhenium complex, ReBr(CO)(5), the carbon-carbo... Umeda, RuiTakahashi, YuukiYamamoto, TakaakiIseki, HidekiOsa...
Selective Catalytic Oxidation of CH Bonds with Molecular Oxygen Although catalytic reductions, cross-couplings, metathesis, and oxidation of CH bonds in alkanes, arenes, or benzylic (allylic) positions, particularly wit... Emil,Roduner,Wolfgang,... - 《Chemcatchem》 被引量: 179发表: 2012年...
the electron localization function (ELF) analysis was performed for all intermediates showing the ionic nature of the studied epoxide structure of GO and rules out any type of covalent interaction during the oxidation reaction of benzyl alcohol. All these obtained results are in good agreement with ...
Selective oxidation of some primary and secondary benzylic alcohols to the corresponding carbonyl compounds with a Cu(III) complex The selective oxidation of benzylic alcohols to the corresponding carbonyl compounds is described. In alkaline solution, the oxidation reagent potassium te... Z Bugarcic,S...
The following reaction is an example of oxidation, with the oxidation number of each atom written below it: −IV+1CH4 + 2 0O2 → +IV - IICO2 +I -II2H2O In this chemical equation, the carbon in methane has an oxida tion number of –IV. The carbon...
Selective Aerobic Oxidation of Benzylic Alcohols Catalyzed by Carbon-Based Catalysts: A Nonmetallic Oxidation System Swapping places: The use of carbon to replace transition metals in the selective aerobic oxidation of benzylic alcohols has been demonstrated to be feasibl...
