Bis(furazano)pyridinone N,N'-dioxide: a new high-density insensitive explosive

The synthesis and properties of novel high-dense energetic material based on new 4 H ,8 H -bis(furazano)[3,4- b :3 ' ,4 ' - e ]-pyridine ring system are described. An operationally simple, efficient and scalable protocol towards 4 H ,8 H -bis(furazano)-[3,4- b :3 ' ,4 ' - e ]pyridin-8-one 1,7-dioxide from commercially available 4-amino-2,6-dichloropyridine in three steps, namely, nitration–azidation–cascade ring closure, has been developed.
