摘要

The nature of the products formed in the diazotization of 5-aminoisoxazoles is controversial,'and such reactions carried out at the same acidity have been reported to give different products. 2 Diazotization in dilute acid or under aprotic conditions leads to either triazene derivatives or 4-isoxazolyl-3, 4-dialkylisoxazol-5-ones. 3 Thermal or photochemical reactions of 5-amino-3, 4-dimethylisoxazole with an excess of an alkyl nitrite are reported ...
