The synthesis of 6-hetarylamino[1,2,4]triazolo[4,3-b][1,2,4,5]tetrazines is reported. The functionalized secondary amines were constructed via a K2CO3-mediated SNAr reaction of weakly basic hetarylamines with 3-(3,5-dimethylpyrazol-1-yl)[1,2,4]triazolo[4,3-b][1,2,4,5]tetrazines, which allowed displacement 3,5-dimethylpyrazolyl leaving group. Significantly, the reaction exhibited a broad substrate scope and proceeded in good yields.

An efficient two‐step one‐pot protocol for the synthesis of N‐nitrated trinitroethylamino furazans in an ionicliquid has been developed involving the condensation of aminofurazans with trinitroethanol and the N‐nitration of an intermediate Mannich base. Trinitroethylnitramino derivatives have been synthesized and characterized by multinuclear NMR spectroscopy and X‐ray crystallography. A role of the

Access to unsymmetrical secondary dihetarylamines through the Cu(OAc)2/2-acetylcyclohexanone catalyzed cross-coupling of s-tetrazinylamines with iodofurazans has been developed. The reaction displays good functional group tolerance, involving nitro, azido, and azo groups, which are critical for the construction of energetic materials. Both 3,6-disubstituted and annelated s-tetrazines react readily
