Abstract:Reaction of vicarious nucleophilic substitution (VNS) of hydrogen was
applied for preparation of 1,3,5-triamino-2,4,6-trinitrobenzene (TATB) in a twostep
process. Using this approach 3-amino-2,4,6`2`4 6` -hexanitrostilbene
(MNHNS) and new 2,6-bis(3-amino-2,4,6-trinitrophenyl)-3,5-dinitropyridine
(DAPYX) were obtained.
