Treatment of 2‐aminopyrimidime, a 4‐aminopyrimidine, aminopyrazine, and 3‐aminopyridazines with O ‐mesilylenesulfonylhydroxylamine gave the corresponding N ‐aminodiazinium salts in high yields. These salts could be transformed into s ‐triazolo[1, 5‐ a ] pyrimidines, s ‐triazolo[1, 5‐ a ]‐pyrazines, s ‐triazolo[1, 5‐ c ]pyrimidines, and s ‐triazolo[1, 5‐ b ]pyridazines hy treatment with acylating agents.
