Guanazine (3,4,5-triamino-1,2,4-triazole) is selectively nitrosated on C–NH 2 to produce nitrosoguanazine (3-nitrosamino-4,5-diamino-1,2,4-triazole). The nitrosoguanazine is used to prepare 5-azido-3-amino-1,2,4-triazole and nitrosoguanazine anion

New quaternary salts of pentafluorosulfanyl-substituted (SF5) N-methylimidazole (1), 4-amino-1,2,4-triazole (3) or pyridine (5) were prepared and characterized. Most of the salts exhibit good thermal stabilities and low melting points placing them in

A process for N-butyl-N-(2-nitroxyethyl)nitramine (BuNENA) was investigated: Step 1 involves N-butyl-ethanolamine addition to 98% HNO3 to form a salt mixture; Step 2 is addition of acetic anhydride/acetyl chloride catalyst to the salt mixture. A numb

Unlike N-alkyl carbamates, N-pentafluorosulfanyl carbamates (SF 5 NHCO 2 R) did not readily undergo nitration to provide the N-NO 2 derivatives. Although trifluoroacetyl nitrate did provide nitration, work-up yielded a mixture of SF 5 N(NO 2 )CO 2 R
