Abstract

The isoxazole proton is sufficiently acidic to give the title salt, hydroxylammonium 4-(ethyloxycarbonyl)-5-oxo-2,5-dihydroisoxazolide, NH3OH+.C6H6NO4-, in the presence of hydroxylamine. The deprotonation of the heterocyclic ring has a profound effect on its geometry, notably increasing the N-O distance by 0.05 A to 1.433 (2) A.
