| 摘 要： | 本文报道了二苯胺、甲基苯基胺、甲潜苄胺、二苄胺、二异丙胺和二乙胺分别与苯并呋咱-1-氧化物在紫外光照下发生光化学反应的电子自旋共振(ESR)研究结果。结果表明:紫外光的作用首先使苯并呋咱-1-氧化物处于激发态,它与二胺作用生成激基态络合物,经氧转移和二胺的氮氢键断裂而最终生成相应的氮氧自由基。

| Abstract: | The photolysis of 2, 1, 3-benzoxadiazole-1-oxide in the presence of various organic amines have been investigated using ESR spectroscopy. Our results show that nitroxide radicals are the stable products of the photooxidation of the corresponding organic amines. Oxygen-transfer exciplex derived from the triplet state of 2,1,3-benzoxadiazole-1-oxide is an intermediate to give nitroxide through N-H bf:id cleavage in the organic amine within the exciplex. |
