利用激光光解3，5-二苯基-1，2，4-恶二唑-4-氧化物（4）生成苯甲酰基硝基苷（5），并对其进行了时间分辨红外光谱研究。测得5与二乙胺和1，3-环己二烯反应的二级速率常数分别为（1.3 ± 0.5）× 105 M-1 s-1和（6.0 ± 0.5）× 103 M-1 s-1。还观察到5与二乙胺反应生成硝酰基（HNO）。
Benzoyl nitroside (5) was generated in solution by laser photolysis of 3,5-diphenyl-1,2,4-oxadiazole-4-oxide (4) and studied by time-resolved infrared spectroscopy. The second-order rate constants for reaction of5with diethylamine and 1,3-cyclohexadiene were determined to be (1.3 ± 0.5) × 105M-1s-1and (6.0 ± 0.5) × 103M-1s-1, respectively. The formation of nitroxyl (HNO), a product of the reaction of5with diethylamine, was also observed.
