reductive coupling of arylbromides with unactivated alkenes is introduced as a convenient method that circumvents any need for synthesis of sp3-hybridized coupling partners. The reaction takes place via photoinduced electron transfer from a tertiary amine to an arylbromide that fragments to provide an aryl radical and subsequently reacts with an alkene to form a C–C bond. Conveniently, the amine also
