The direct and efficient oxidation of tertiary benzylic CH bonds to alcohols with O2 was accomplished in the presence of metalloporphyrins as catalysts undersolvent-free and additive-free conditions. Based on effective inhibition on the unselective autoxidation and deep oxidation, systematical investigation on the effects of porphyrin ligands and metal centers, and apparent kinetics study, the oxidation
Unusual Inhibition Effect of 1-(1-Naphthyl)-1-methylethylhydroperoxide on the Liquid-Phase Oxidation of Isopropylarenes. GC−MS and Theoretical Studies of the Thermal Decomposition of 1-Naphthyl- and 1-Anthryl-1-methylethylhydroperoxides
have thus far never been described as thermaldecomposition products of 1-aryl-1-methylethylhydroperoxides. The plausible mechanism of the formation of 2-(1-aryloxy)propenes was proposed on the basis of AM-1 calculations of the possible rearrangement paths of the alkoxy radicals derived from the investigated hydroperoxides. The mechanism explains the inhibition effect of 1-(1-naphthyl)-1-methylethylhydroperoxide
