TiO2 photocatalysis can be performed for the addition of pyridines to vinylarenes in an anti-Markovnikov manner. Seven examples with considerable yields (56-91%) and selectivity were demonstrated. A comparative survey of the involved process through ESR revealed a novel concerted two electron transfer pathway for these photocatalytic bimolecular addition reactions.
二氧化钛光催化可用于以反马氏规则的方式将吡啶加成到乙烯基芳烃上。展示了七个具有可观产率（56 - 91%）和选择性的例子。通过电子自旋共振对相关过程进行的比较研究揭示了这些光催化双分子加成反应的一种新型协同双电子转移途径。
