摘要：

The tautomerism of isoxazolin-5-ones was investigated by experimental determination of the dipole moments of several isoxazoline-5-ones, N-methylisoxazoline-5-ones and 5-methoxyisoxazoles. Experimental values were then compared with the theoretical ones obtained by vector addition of the σ and π moments. Our results show that isoxazolin-5-ones in dioxan can exist in all the three allowed tautomeric forms, though the ketonic forms are generally predominant. © 1977.
