The pyrolysis of 1-aroylamino-4,5-diphenyl-1,2,3-triazoles 1 yields, pressumably via the 4,5-diphenyl-1,2,3-triazolyl radical (2a), 2,3-diphenyl-2H-azirine (11a) and 2-aryl-4,5-diphenylimidazoles 14 as the major products. Upon irradiation 1-benzoylamino-4,5-diphenyl-1,2,3-triazole (1a) gives 4,5-diphenyl-1 (2)H-1,2,3-triazole (4a) via the 1,2,3-triazolyl radical 2a, together with benzamide (5a) and
1-芳酰基氨基-4,5-二苯基-1,2,3-三唑1的热解可加压地通过4,5-二苯基-1,2,3-三唑基(2a),2,3-二苯基- 2 H- azirine(11a)和2-芳基-4,5-二苯基咪唑14是主要产物。辐射后1-苯甲酰氨基-4,5-二苯基-1,2,3-三唑(1a)通过1,2得到4,5-二苯基-1(2)H -1,2,3-三唑(4a),3-3-三唑基自由基2a以及苯甲酰胺(5a)和1,2-双苯甲酰肼(6a)。产品5a和6a苯甲酰氨基基团3a分别通过氢原子的提取和二聚作用产生。
