Abstract

Kinetic studies 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.
