Abstract: The photolysis (W light) of acyl derivatives of N-hydroxy-2-thiopyridone in pyridine- acetic acid permits a study of the partitioning of secondary radicals between oxygen, pyridine, and the thione function. Comparison with the GiPv oxidation system for saturated hydrocarbons confirms that radicals are not involved in oxidation at secondary positions. On the contrary, radical behavior at the tertiary position in adamantane is again established. ...
