Study of Synthesis of N-Nitroborazine Compounds. I. Nitryl Chloride as Nitrating Agent.
Abstract
While assessing nitryl chloride (NO2Cl) as a possible nitrating agent for borazine and its derivatives, an analysis of several infrared spectra indicated that samples of nitryl chloride were contaminated with nitrosyl chloride (NOCl). Considerable attention was focused on the source of nitrosyl chloride and on means for its removal. A purification procedure was ultimately developed consisting of the simultaneous precipitation of NOCl and dinitrogen tetroxide (N2O4) as the solid complexes of boron trifluoride (BF3). Nearly water-white nitryl chloride was obtained in this manner. A tinge of yellow was attributed to the presence of chlorine. The reaction of nitryl chloride with a model compound, lithium dimethylamide, was found to yield dimethylnitramine as one of the reaction products. This is in contrast to previous studies made on the gas phase reactions of nitryl chloride with ammonia and several amines. A discussion is presented in view of these contrasting results. (Author)
