Reaction of O atoms produced by CO2 discharge with cycloalkanes leads to their hydroxy, keto, and epoxy derivatives.The main products of oxidation of isomeric 1,2-dimethylcyclohexanes and cis-decalin were their respective tertiary alcohols formed with a high retention of configuration.This oxidation proceeds via radical mechanism, and the alcohols are formed by radical combination in a solvent cage.The influence of temperature and of O2 on the relative product distribution was investigated.
