The Chemistry of 5-Oxodihydroisoxazoles. Part 23. Photochemical and Thermal Reactions of Isoxazol-5(2 H )-ones substituted at C-3 or C-4 with Nitrogen,Oxygen or Sulfur

Abstract

3-Amino- and 3-hydroxy-isoxazol-5(2H)-ones can exist as a number of tautomers which give discrete photolysis and pyrolysis products.
