A site-specific oxidation of (sp3)C-C(sp3) and (sp3)C-H bonds in aryl alkanes by the use of NaNO2/HCl was explored. The method is chemical-oxidant-free, transition-metal-free, uses water as the solvent, and proceeds under mild conditions, making it valuable and attractive to synthetic organic chemistry.

Abstract: In the temperature range of 703–763 K, the thermal stability of 4-tert-butyl diphenyl oxide (4?TBDPO) has been studied, the components of the thermolysis reaction mass have been identified, a kinetic model of the process has been proposed, and the rate constants and parameters of the Arrhenius equation for all reactions under consideration have been calculated. The predominant role of isomerization transformations of 4-TBDPO has been found. A mechanism for the radical isomerization of the tert-butyl substituent has been proposed.

The relative rates of reaction of a series of p-substituted cumenes with dimethyldioxirane have been studied.The products are the corresponding cumyl alcohols.Treatment of the rate data with the Hammett substituent constants reveals that the insertion reaction is an electrophilic process with ρ = -2.76.Similar tretment of the data with the Brown-Okamoto substituent constants gives ρ+ = -1.61.The second-order rate constants for the reaction of a series of substituted adamantanes with dimethyldioxirane were also determined.Again, the products are the corresponding adamantanols.The rate constants were correlated with several types of substituent constants.The best correlations were obtained with the Taft ?* and ?I constants which gave ρ* = -1.08 and ρI = -2.39, respectively.Thus, the insertion reaction in this aliphatic system is also electrophilic.
Substituent effects on benzyl radical hyperfine coupling (hfc) constants. Part 3. Comparison of the α-hfc for substituted benzyl radicals with the β-hfc for substituted cumyl radicals

The electron spin resonance (esr) spectra of eighteen para-substituted cumyl radicals were analyzed.The relationship between the β-hyperfine coupling (β-hfc) constants of these cumyl radicals and the corresponding α-hfc constants of benzyl radicals was studied.Although there is a general trend for the α- and β-hfc values to vary in a similar manner, specific deviations from a linear correlation between these parameters were observed.These deviations were rationalized by considering charge effects on spin delocalization.The correlation coefficient for the linear regression analysis of these α- and β-hfc values was found to significantly improve when parameters reflecting charge effects on spin delocalization were included in an extended Hammett treatment of the spectral data.
