Benzophenone is photoreduced by pthalimidines and dihydro isoquinolones. The hydrogen atom α to the nitrogen atom is abstracted and radical coupling leads to adducts. CIDNP studies of these adducts show inversion of polarisation for the adduct on the N-alkyl chain when the nitrogen is bound to a benzylic methylene. This inversion is explained by considering that the radical on the N-alkyl chain derives
二苯甲酮被邻苯二甲酰亚胺和二氢异喹啉酮光还原。氢原子α到氮原子被抽象,自由基偶联导致加合物。这些加合物的CIDNP研究表明,当氮与苄基亚甲基键合时,N-烷基链上的加合物的极化反转。通过考虑N-烷基链上的基团衍生自环上的基团来解释这种转化。
