The hexanitrohexaazaisowurtzitane(HNIW) is a polycyclic caged nitramine oxidizer. For most existing weapons systems, the most critical ingredient in explosive and propellant applications is the oxidizer, HNIW, with its increase in performance output and energy capabilities for future in explosive and propellant systems. Two new polyacylhexaazaisowurtzitanes were synthesized. Pentaacetylhexaaza-isowurtzitane(PAIW) or pentaacetylformylhexaazaisowurtzitane(PAFIW) can be a precursor in the preparation of HNIW, recently developed highly energetic material.
