- THE KINETICS OF THE REACTIONS OF 2,6-DI-t-BUTYL-4-METHYLPHENOL AND 2,4,6-TRIMETHYLPHENOL WITH NITROGEN DIOXIDE IN SOLUTION
-
The reaction of 2,6-di-t-butyl-4-methylphenol with nitrogen dioxide to form 2,6-di-t-butyl-4-methyl-4-nitrocyclohexa-2,5-dienone has a first order dependence of rate on the concentration of the species N2O4.By contrast the observed rate of the correspondi

- Site-Specific Oxidation of (sp3)C-C(sp3)/H Bonds by NaNO2/HCl
-
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.

- New insights into the reactivity of nitrogen dioxide with substituted phenols: A solvent effect
-
Various alkyl-substituted phenols react readily with nitrogen dioxide (.NO2) in different solvents at room temperature. In all cases nitration is the major reaction and leads to the formation of mono- and dinitrophenols and 4-nitrocyclohexa-2,5-dienones from 2,4,6-tri-substituted phenols. Oxidation, dimerisation and, in one case, nitrosation are also observed. The reaction pathway followed changes according to the solvent and to the nature and the number of substituents on the phenolic ring. Wiley-VCH Verlag GmbH & Co. KGaA, 2005.
