Aromatic hydroxylation by O( 3 P) atoms on γ-radiolysis of liquid carbon dioxide solutions of alkylbenzenes

Hydroxylated products have been produced by the attack of O(3P) atoms, generated by γ-radiolysis of liquid CO2, on alkylbenzene at the following sites: aromatic methine carbon, aromatic ring carbon bearing a substituent accompanied by 1,2-shift of the substituent (NIH shift) or removal of the substituent, and alkyl substituent.
