The first trinitromethyl-substituted pyrimidine derivative (3) was synthesized by directly nitration of its 2-methylpyrimidine precursor, and its structure was characterized by various analytical techniques. Compound 3 exhibited high density (1.85 g cm-3) and excellent detonation performances (vD = 8600 m s-1, P = 32.8 GPa), indicating its potential as a high-energy density material. Moreover, this study provides a mild and efficient method for the synthesis of trinitromethyl-substituted pyrimidine derivatives, which may have potential applications in the design and synthesis of other trinitromethyl-based heterocyclic compounds.
The first trinitromethyl-substituted pyrimidine derivative (3) was synthesized by direct nitration of its 2-meth-ylpyrimidine precursor, and its structure was thoroughly characterized by FTIR, NMR, elemental analysis, and single-crystal X-ray diffraction. Compound 3 has a high density (1.85 g cm-3) and excellent detonation per-formances (vD = 8600 m s- 1, P = 32.8 GPa), which highlights its great potential as high-energy density material. Furthermore, this work provides a mild and efficient method for the synthesis of trinitromethyl-substituted pyrimidine derivatives, which might have potential application in the design and synthesis of other trinitromethyl-based heterocyclic compounds.
