Study of palladium catalyst deactivation in synthesis of 4,10-diformyl-2,6,8,12-tetraacetyl-2,4,6,8,10,12-hexaazaisowurtzitane

Polycyclic nitramine hexanitrohexaazaisowurtzitane (HNIW, CL-20) is synthesized via hydrodebenzylation of a precursor over palladium-based catalyst. In the present work, we studied the influence of the synthesis method of the palladium-based catalyst on the catalyst behavior during the hydrodebenzylation reaction of 2,4,6,8,10,12-hexabenzyl-2,4,6,8,10,12-hexaazatetracyclo[5.5.0.0(3,11).0(5,9)] dodecane.
