“…The further oxidation is favoured 46 when it is carried out at temperatures of 150°C in butanoic acid as solvent. It must be established that in the case of ethylbenzene, the further oxidation of acetophenone takes place very slowly compared to the oxidation of the starting hydrocarbon so that higher yields of acetophenone can be obtained 47,48 . As like in the case of other tertiary alcohols, the mechanism of the further oxidation of 2-phenylpropane-2-ol is exactly not known.…”

Hydroperoxide atα-position to the aromatic ring is the primary oxidation product formed. In all cases monoalkylbenzenes lead to the formation of benzoic acid. Oxidation in the presence of transition metal salts not only accelerate but also selectively decompose the hydroperoxides. Alkyl naphthalenes mainly produce the corresponding naphthalene carboxylic acids. Hock-rearrangement by the influence of strong acids converts the hydroperoxides to hemiacetals. Peresters formed from the hydroperoxides undergo Criegee rearrangement easily. Alkali metals accelerate the oxidation while CO2as co-oxidant enhances the selectivity. Microwave conditions give improved yields of the oxidation products.

“…More recently, semiempirical quantum mechanical techniques have been used to study glycyl and alanyl residues,4 polypeptide chains,6 and model peptide molecules. 6 We have presented the results of a detailed study by extended Hückel theory (EHT) of the helical conformations of a tetrapeptide of glycine which is long enough to incorporate an intramolecular hydrogen bond. We have also presented the corresponding results using the CNDO/2 method on this system.…”

The consumption of labeled methylphenylcarbinol during the liquid-phase oxidation of ethylbenzene at 120" has been investigated. Oxidation of the carbinol yielded only acetophenone, but most of the latter was formed directly, by the termination reaction and by decomposition of hydroperoxide molecules. Use of the modified kinetic isotope method permitted quantitative calculation of rates of formation of alcohol and ketone molecules by various routes.

“…S21, ESI †). 36,[38][39][40] First, the exposed, active Co II species on the crystal surface preferentially interacts with the O-O moiety in TBHP and loses a single electron to the highly destabilized state. This results in homolytic O-O bond cleavage to generate the tert-butyl oxygen radical and Co III -OH species.…”
