- Reductive debenzylation of hexabenzylhexaazaisowurtzitane - The key step of the synthesis of polycyclic nitramine hexanitrohexaazaisowurtzitane
-
Main features of the reductive debenzylation of 2,4,6,8,10,12-hexabenzyl-2, 4,6,8,10,12-hexaazaisowurtzitane were studied. This process is the key step of the synthesis of 2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaazatetracyclo[5.5.0. 03,11.0s
