β-nitro- and β-bromo-β-nitrostyrenes in the reactions with aminonitroguanidine
摘要:
The conditions for the reactions of beta-nitro- and beta-bromo-beta-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.
