β-nitro- and β-bromo-β-nitrostyrenes in the reactions with aminonitroguanidine

The conditions for the reactions of ??-nitro- and ??-bromo-??-nitrostyrenes with 1-amino-2-nitroguanidine resulting in the amination products, 1-nitro- and 1-bromo-1-nitro-2-aryl-2-(2-nitroguanidinoamino) ethanes, were found. Under the action of the basic catalysts or prolonged boiling, the adducts derived from the gem-bromonitrostyrenes undergo decomposition to form N-arylmethylidene-N-(2-nitroguanidino)amines.
