HNIW (2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaazaisowurtzitane) is one of the high energy density cage nitramines, which has so many versatile applications. Several variable intermediates and synthesis route have been applied for the preparation of HNIW. One of the significant intermediate for the synthesis of HNIW is TADB (2,6,8,12-tetra acetyl-4,10-dibenzyl hexa azaisowutzitane). The present investigation focuses on debenzylation of TADB for preparation of TAIW (2,6,8,12-tetra acetyl hexa azaisowurtzitane) as a key step in the synthesis of HNIW, by application of cerium (IV) ammonium nitrate and KBrO3 simultaneously in order to overcome the obstacle of malfunction of CAN. Experiments carried out with variation of some parametric conditions like time, mole ratio of CAN and KBrO3. In optimum condition the reaction yield increased to 80%.
