Chemistry of urea nitro derivatives: II. Synthesis of nitramide from N,N′-dinitrourea. New reactions of nitramide

10.1023/A:1015334703526

The research focuses on the chemistry of urea nitro derivatives, specifically the synthesis of nitramide from N,N'-dinitrourea and subsequent reactions of nitramide. The study developed convenient procedures for synthesizing nitramide based on urea through the hydrolysis of N,N'-dinitrourea, which is highly reactive and sensitive to mechanical disturbance. The experiments involved various reactants such as urea, N,N'-dinitrourea, water, sulfuric acid, ammonium nitrate, and water-saturated solvents with low dielectric constants. The analyses used to monitor the reactions and characterize the products included infrared (IR) and ultraviolet (UV) spectroscopy, as well as kinetic measurements to determine the rate constants of the hydrolysis reactions. The study also explored nitramide's decomposition in acid media and its reactions with formaldehyde, ethyl acetate, and acetic anhydride, leading to the formation of various compounds like dinitramide, methylenedinitramine, and N-nitroacetamide.
