Article abstract of DOI:10.1007/BF00959722

The reaction of 4-amino-1-phenacyl-1,2,4-triazolium bromides with an excess of nitrous acid leads to a mixture of the corresponding ω-(1,2,4-triazol-1-yl)-acetophenones and ω-hydroximino-ω-(1,2,4-triazol-1-yl)acetophenones. Products of the latter type are
