1 引言 光引发的自由基链式亲核取代SR。且反应是自由基反应与离子型反应的交叉结合,这不仅从理论上对深人理解单电子转移反应有着重要的意义,
1 Introduction Photo-initiated free-radical nucleophilic substitution of SR. And the reaction is the cross-linking reaction of radical reaction and ionic reaction, which is of great significance not only theoretically understanding the single-electron transfer reaction,
