Abstract

3-Hydroxy-2-methyl-4-phenylisoxazol-5 (2)-one exists as four tautomers, two of which are isolated and characterised; photolysis in methanol leads to formation of products identified as arising uniquely from three of the tautomers, and the 2-phenyl analogue and phenyldisic acid undergo similar photochemical reactions
