Abstract
Isoxazole- and 4,5-dihydroisoxazole-3-carboxylic acid amidoximes were obtained in the reaction of 5-trifluoromethyl-1,2,4-oxadiazole-3-carbohydroximic acid bromide in the presence of sodium bicarbonate with monosubstituted ethylenes and acetylenes with subsequent opening of the oxadiazole ring. Amidoximes of the isoxazole series undergo rearrangement to aminofurazans under the influence of alkalis.
