5-Phenyl-tetrazole은 光分解하면 질소 한 分子를 放出하며 1,3-dipole인 C-phenyl-nitrilei-mine을 形成한다. 그러나 이때 dipolarphile의 存在下에서 1,3-dipole-cyclo-addition은 일으키지 않으며 二重合體인 3,6-diphenyl-1,4-dihydro-1,2,4,5-tetrazine(III)을 거쳐 最終産物로서 3,6-diphenyl-1,2,4,5-tetrazine(IV), 2,5-diphenyl-1,2,4-triazole, 4-amino-3,5-diphenyl-1,2,4-triazole, benzonitrile, ammonia 그리고 nitrogen을 生成한다.
The main object of this experiment is to provide a systematic approach to the reaction mechanism in the photolysis of 5-phenyl-1,2,3,4-tetrazole during which the formation of C-phenyl-nitrile-imine of 1.3-dipole was expected. So the occurrence of 1,3-dipole-addition was examined but not observed despite the formation of nitrile-imine. 3,6-diphenyl-1,2,4,5-tetrazine (IV); 3,6-diphenyl-1,4-dihydro-1,2,4,5-tetrazine (III); 3,5-diphenyl-1,2,4-triazole; 4-amino-3,5-diphenyl-1,2,4-triazole; benzonitrile; ammonia and nitrogen were isolated as final products of this reaction.
