Based on the acid-base neutralization, the (1-methylimidazolium)(tetrazol-1-yl)borane was successfully synthesized by taking advantage of the acidity of the tetrazole and the basicity of the 1-methylimidazole borane complex. Through HRMS, NMR, and FT-IR, the structure of synthetic compounds was characterized in detail. Concerning about the (1-methylimidazolium)(tetrazol-1-yl)borane, it had an ignition-delay time of about 25 ms and a density specific impulse over 351 s·g/cm, making it a suitable candidate for green hypergolic fuels. Moreover, it also demonstrated that introducing tetrazole into the borane could be an appropriate strategy to adjust the performance of the energy of those borane compounds.
基于酸碱中和反应，利用四唑的酸性和 1-甲基咪唑硼烷配合物的碱性，成功合成了(1-甲基咪唑)(四唑-1-基)硼烷。通过高分辨质谱、核磁共振和傅里叶变换红外光谱，详细表征了合成化合物的结构。对于(1-甲基咪唑)(四唑-1-基)硼烷，它的点火延迟时间约为 25 毫秒，密度比冲超过 351 秒·克/厘米，使其成为绿色自燃燃料的合适候选物。此外，还表明将四唑引入硼烷中是调节这些硼烷化合物能量性能的一种合适策略。
