the two-step process of debenzylation during which the compound is rapidly deactivated. The expensive Pd/C catalyst is deactivated in the first step of the process, which limits the use of this polycyclic nitramine. The influence of the solvent nature; loadings of the reactants, catalyst, and cocatalyst; the hydrogen pressure and reaction temperature on the general features of the process and the yield
研究了 2,4,6,8,10,12-hexabenzyl-2,4,6,8,10,12-hexaazaisowurtzitane 还原脱苄的主要特征。该工艺是合成2,4,6,8,10,12-六硝基-2,4,6,8,10,12-六氮杂四环[5.5.0.03,11.05,9]十二烷(hexanitrohexaazaisowurtzitane, CL-20),一种具有独特能量和爆炸特性的化合物。到目前为止,后者的使用受到两步脱苄过程的高成本的限制,在该过程中化合物迅速失活。昂贵的 Pd/C 催化剂在该过程的第一步中失活,这限制了这种多环硝胺的使用。溶剂性质的影响;反应物、催化剂和助催化剂的负载量;
