Based on N-B bonds, a novel strategy was developed for improving the energetic performance of tetrazoles. By employing the amino neighboring group participation, the azolyl borane compound 7 was selectively constructed, which exhibited excellent stability in water and air. This strategy solved the acidity problem of tetrazole as well as increasing the heat of detonation and combustion by 25% and 36%, respectively. Through laser ignition experiments, it also improved the combustion performance of tetrazoles. In DSC experiments, thermal decomposition temperatures of N-B covalent compounds were elevated as well. In an electrostatic potential calculation and sensitivity test, N-B covalent compounds exhibited good sensitivity (IS > 40 J and FS > 360 N). Through TG-DSC-FTIR-MS and in situ IR experiments, decomposition products were investigated to determine the next optimization stage for heat of detonation. It offered a significant potential for development to incorporate the N-B bond into nitrogen-rich compounds.
