Routes examined include condensation of amides with an orthoformate, reaction of tris(acylamino) methanes with orthoformate and cyclizations based on acylated perhydrotriazines. The cyclization chemistry of a pentaazabicyclononadiene is also under investigation. Several routes to tetranitrazabicyclooctane ('bicyclic HMX') have also been examined including modification of the preformed tetraazabicyclooctane ring system and cyclization approaches. (Author) 收起
