Castellanos-Soriano, Jorge published the artcilePhotoredox catalysis powered by triplet fusion upconversion: arylation of heteroarenes, Related Products of benzothiophene, the main research area is furan thiophene arylation photoredox catalysis; Arylations; Furans; Photon upconversion; Photoredox catalysis; Thiophenes; Triplet fusion (triplet–triplet annihilation); Visible light.

In this work, the feasibility of triplet fusion upconversion (TFU, also named triplet-triplet annihilation upconversion) technol. for the functionalization (arylation) of furans and thiophenes has been successfully proven. Activation of aryl halides by TFU leads to generation of aryl radical intermediates; trapping of the latter by the corresponding heteroarenes, which act as nucleophiles, affords the final coupling products. Advantages of this photoredox catalytic method include the use of very mild conditions (visible light, standard conditions), employment of com. available reactants and low-loading metal-free photocatalysts, absence of any sacrificial agent (additive) in the medium and short irradiation times. The involvement of the high energetic delayed fluorescence in the reaction mechanism has been evidenced by quenching studies, whereas the two-photon nature of this photoredox arylation of furans and thiophenes has been manifested by the dependence on the energy source power. Finally, the scaling-up conditions have been gratifyingly afforded by a continuous-flow device.
