A new, three-stage synthesis of 1,3,5-triamino-2,4,6-trinitrobenzene (TATB) has been developed which avoids the use of halogenated precursors or reagents. The starting material, 1,3,5trihydroxy-benzene, is converted via the sequence nitrationalkylation-amination to TATB in an overall yield of 87%. T
