Zusammenfassung:The degenerative transfer of xanthates to olefins is enabled by the iridium-based photocatalyst [Ir{dF(CF )ppy} (dtbbpy)](PF ) under blue LED light irradiation. Detailed mechanistic investigations through kinetics and photophysical studies revealed that the process operates under a radical chain mechanism, which is initiated through triplet-sensitization of xanthates by the long-lived triplet state of the iridium-based photocatalyst.
