Combined Photoredox and Iron Catalysis for the Cyclotrimerization of Alkynes

[EN] Successful combinations of visible-light photocatalysis with metal catalysis have recently enabled the development of hitherto unknown chemical reactions. Dual mechanisms from merging metal-free photocatalysts and earth-abundant metal catalysts are still in their infancy. We report a photo-orga...

Dual mechanisms from merging metal-free photocatalysts and earth-abundant metal catalysts are still in their infancy. We report a photo-organo-iron-catalyzed cyclotrimerization of alkynes by photoredox activation of a ligand-free Fe catalyst. The reaction operates under very mild conditions (visible light, 20 degrees C, 1 h) with 1-2 mol % loading of the three catalysts (dye, amine, FeCl2).This work was supported by the Fonds der Chemischen Industrie (to M.N.) and the European Research Council (CoG 683150).
