Abstract

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.
