用激光闪光光解技术研究了几种含氟芳基叠氮化合物（2，6和2，4-二氟苯基叠氮、2，4，6-三氟苯基叠氮和4-叠氮基-2，3，5，6-四氟苯甲酸甲酯）。在每种情况下，叠氮化物形成单线态氮烯，其可以被吡啶拦截以形成叶立德。这允许的单线态氮烯的脱氢氮杂卓和测量的绝对速率常数的单线态氮烯与典型的猝灭剂的反应的速率常数的环膨胀的速率常数的测定。
Several fluorinated aryl azides (2, 6 and 2, 4-difluorophenyl azide, 2, 4, 6-triflurorophenyl azide, and methyl 4-azido-2, 3, 5, 6-tetrafluorobenzoate) were studied by laser flash photolysis techniques. In each case, the azides form singlet nitrenes which can be intercepted with pyridine to form ylides. This allowed determination of the rate constant for ring expansion of the singlet nitrene to the dehydroazepine and measurement of the absolute rate constants for reaction of the singlet nitrenes with typical quenchers.
