The N-fluoropyridinium tetrafluoroborate reactions with carbanions were found either to follow the cine -(tele)-AEa-substitution or go through possible formation of a carbenic (cationic) intermediate; as a result 2- or 4-pyridyl derivatives are formed.

Pyridine derivatives based on the addition of trinitromethyl functional groups were synthesized by the reaction of N₂O₄ with the corresponding pyridinecarboxaldoximes, then they were converted into dinitromethylide hydrazinium salts. These energetic compounds were fully characterized by IR and NMR spectroscopy, elemental analysis, differential scanning calorimetry (DSC), and X-ray crystallography.
通过N 2 O 3与相应的吡啶羧醛肟的反应合成基于三硝基甲基官能团的吡啶衍生物,然后将其转化为二硝基甲基肼盐。这些高能化合物已通过IR和NMR光谱,元素分析,差示扫描量热法(DSC)和X射线晶体学进行了全面表征。这些吡啶衍生物具有良好的密度,正的形成焓和可接受的灵敏度值。使用高斯03和EXPLO5程序进行的理论计算显示出良好的爆轰速度和压力。这些化合物的每种性能均优于TNT,而2,6-双(三硝基甲基)吡啶(D = 8700 m·s-1,P = 33.2 GPa)具有与RDX相当的爆炸性能,
