✦ Synopsis

In a previous paper of this series, it has been shown that several hindered phenols undergo dye-sensitized photooxygenation to give various oxidation products. For example, 2,6di-t-butylphenol (l~ yielded 2,6-di-t-butyl-p-benzoquinone (2~ and 3,5,3',5'-tetra-t-butyl-4,4'-diphenoquinone (~ besides some polymers.

We suggested that, as shown in Scheme i,

An important step in the initial oxidation of hydrocarbons at low to intermediate temperatures is the abstraction of H by hydroperoxyl radical (HO(2)). In this study, we calculate energy profiles for the sequence: reactant + HO(2) β†’ [complex of reactants] β†’ transition state β†’ [complex of products] β†’

The homolysis of a Co-C bond accompanied by hydrogen abstraction from environmental molecules giving rise to the new Co-C bond formation with the molecules is of particular interest in connection with the reaction mechanism of the vitamin B12 dependent dehydrase.'
