摘要：
A new simple and efficient approach to 2,4-disubstituted 1,2,3-triazoles-5-amines from the reaction of 2-arylhydrazononitriles and hydroxylamine is described. Investigation of behavior of 3-phenyl-3oxo-2-arylhydrazonopropane nitriles has been undertaken. In addition to readily reported formation of aminoisoxazoles, 4-benzoyl-1-aryl-1,2,3-triazole-5-amines 5f,g were prepared via cyclising products of reacting 2f,g with hydroxylamine in basic medium.
