Photoinduced electron-transfer (PET) reactions of 1,4-diphenyl-2,3-diazabicyclo[2.2.2]oct-2-ene 1 result in a quantitative formation of 2,5-diphenylhexa-1,5-diene 2, in sharp contrast to the results of non-PET reactions and showing the importance of a back electron-transfer (BET) process in PET reactions.
1,4-二苯基-2,3-二氮杂双环[2.2.2]辛-2-烯 1 的光诱导电子转移(PET)反应可定量生成 2,5-二苯基六-1,5-二烯 2,这与非 PET 反应的结果形成了鲜明对比,并显示了反向电子转移(BET)过程在 PET 反应中的重要性。
