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 so
