Polynitro compounds, aliphatic

Various hypotheses have been put forward concerning the mechanism of this reaction. It seems that the reaction is rather complicated, and that the reaction of polynitro compounds with alkalies in alcohol (14, 15,16), as well as the reaction of dinitro compounds with aliphatic amines and diamines, most recently carried out in dimethylformamide or dimethyl sulfoxide, or the reaction with alkali cyanides, also belong to this type of color reactions. 

A comprehensive discussion of the synthetic methods used to introduce the nitro group into aliphatic compounds, and its diverse chemistry, would require more space than available in this book. While every effort has been made to achieve this, some of these methods are given only brief discussion because they have not as yet found use for the synthesis of energetic materials, or their use is limited in this respect. The nature of energetic materials means that methods used to introduce polynitro functionality are of prime importance and so these are discussed in detail. Therefore, this work complements the last major review on this subject. ... 

A new general method of preparing polynitro aliphatic compounds was recently described by Frankel [92], The reaction consists in acting with 2-bromo-2,2-dinitro-ethyl acetate (I) on metallic salts of organic and inorganic compounds having active hydrogen atoms. 

However, most of the polynitro aliphatic compounds show relatively low stability and high sensitivity and these facts have limited their practical usefulness [119). The author of the present book w lll describe only ...

Attention should be drawn to the fact that polynitro aliphatic compounds such as 1,1-dinitroalkanes and trinitromethane exhibit a cloud in aqueous solutions. This is attributed to the presence of the anion [8].
