The first trinitromethyl-substituted pyrimidine derivative (3) was synthesized by direct nitration of its 2-methylpyrimidine 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 performances (vD = 8600 m s−1, P = 32.8 GPa), which highlights its great potential
第一个三硝基甲基取代的嘧啶衍生物 ( 3 ) 是通过其 2-甲基嘧啶前体直接硝化合成的,其结构通过 FTIR、NMR、元素分析和单晶 X 射线衍射进行了全面表征。化合物3具有高密度 (1.85 g cm -3 ) 和优异的爆轰性能 ( v D = 8600 m s -1 , P = 32.8 GPa),凸显了其作为高能量密度材料的巨大潜力。此外,该工作为三硝基甲基取代嘧啶衍生物的合成提供了一种温和高效的方法,可能在其他三硝基甲基杂环化合物的设计和合成中具有潜在的应用价值。
