New polynitramino compounds were synthesized and fully characterized using IR and multinuclear (1H, 13C, 15N) NMR spectroscopy, and elemental analysis as well as single-crystal X-ray diffraction.

A composition and method of manufacturing the same. Embodiments of an aspect of the invention relate to the formula C(CH2NF2)4 having the name octafluoropentaerythrityltetramine (octafluoro-PETA). In embodiments of another aspect generally relate to a method for manufacturing octafluoropentaerythrityltetramine (octafluoro-PETA) including, basifying pentaerythrityltetramine tetrahydrochloride in an aqueous solution with an aqueous alkali and treating with alkyl chloroformate for producing a tetraalkyl pentaerythrityltetra carbamate, extracting the compound into a nonaqueous solvent suitable for extraction from water and removing the solvent for providing a pure form of tetraethyl pentaerythrityltetracarbamate, bubbling elemental fluorine and/or mixtures of fluorine with an inert gas through tetraalkyl pentaerythrityltetracarbamate in a solvent suitable for direct fluorinations of protected amines until excess fluorine appears, and purifying the resultant octafluoropentaerythrityltetramine.
