Degenerative xanthate transfer to olefins under visible-light photocatalysis

The degenerative transfer of xanthates to olefins is enabled by the iridium-based photocatalyst [Ir{dF(CF(3))ppy}(2)(dtbbpy)](PF(6)) under blue LED light irradiation. Detailed mechanistic investigations through kinetics and photophysical studies revealed that the process operates under a radical cha...

description The degenerative transfer of xanthates to olefins is enabled by the iridium-based photocatalyst [Ir{dF(CF(3))ppy}(2)(dtbbpy)](PF(6)) 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.
