on photosensitized oxygenation of 1,3,5-triaryl-2-pyrazolines show that an electron-transfer from the pyrazoline to singlet oxygen may take place to give a cation radical and superoxide ion pair. The reaction of pyrazoline cation radicals with superoxide ion shows the same product distribution with singlet oxygenation.

吡唑啉的光敏氧化的动力学研究表明,可能发生电子从
吡唑啉转移到单线态氧,从而生成阳离子自由基和超氧离子对。
吡唑啉阳离子自由基与超氧离子的反应在单线态氧合下显示出相同的产物分布。
