摘要：

A 13C NMR study of new isoxazol‐5‐ones has been carried out in different solvents. Mathematical analysis of the tautomeric ring proton exchange in pyridine solvent indicates that the relative contributions of the NH, CH and OH tautomers are respectively 10 ± 5, 15 ± 3, 10 ± 8%, while the anionic form represents the remaining 65 ± 8%.
