Photolysis of 3-hydroxyisoxazoles.
Agricultural and Biological Chemistry, 1974 Photolysis of 3-hydroxy-5-phenylisoxazole in methanol with a low-pressure mercury lamp afforded 5-phenyl-4-oxazolin-2-one, together with small amounts of benzoic acid and benzoylacetamide. Similarly, 3-hydroxy-5-methylisoxazole in distilled water afforded 5-methyl-4-oxazolin-2-one as the major product.

Photolysis of Organic Disulphides [PDF]
Nature, 1948 THE reactions following light absorption by pure organic disulphides in solution have not been studied, although the reactions are of great importance in the chemistry of wool, affecting both felting and shrinkage of the wool1,2. Similar reactions occur in irradiated milk3 and in petrol4.
