Reaction of dibenzoylfuroxane with primary aliphatic amines and methylhydrazine

Mixtures of products of the reaction of dibenzoylfuroxane with isopropylamine, tert-butylamine, and methylhydrazine were separated by high-pressure liquid chromatography. According to the proposed reaction scheme, benzamidoglyoxime is formed in the first step, after which it undergoes cyclization to give an N-substituted 3-amino-4-nitroso-5-phenylisoxazole or decomposes via the mechanism of a Beckmann rearrangement of the second type.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 5, pp. 616–619, May, 1978.
