The previously unknown secondary amides of 1,1-dinitroalkanecarboxylic acids were prepared by the reaction of polynitroimidoyl fluorides with water in the presence of mineral acids.They are inert with respect to electrophiles, but react with nucleophiles with the cleavage of the C-C bond between the carbonyl C atom and the C atom of the dinitromethylene group.An X-ray structural study of the amides was carried out and their thermochemical characteristics were determined. - Key words: aldimines, amides of 1,1-dinitroalkanecarboxylic acids, conversions; bond cleavage; carbamates, ureas; orbital interactions; conformation; heat of combustion; the enthalpy of formation.
