Abstract
Reactivity of N-dinitromethylazoles possessing extremely high CH acidity (pKa –1.75–0) was investigated in Michael, Henry and alkylation reactions. N-Dinitromethylazole K-salts and hexamethylenetetramine under acidic conditions yield bis-Mannich bases (86–100%) whose secondary amine moiety can be N-nitrated with HNO3–H2SO4 system.
