Abstract
AbstractElectron‐rich alkoxy‐substituted (hetero)arenes and electrophilic fluoroalkyl moieties represent advantageous partners for substitution reactions due to their electronic match. Fluoroalkylation strategies of alkoxy‐substituted (hetero)arenes are herein presented which depict photocatalytic and thermal methods. Photocatalytic methods rely on the use of diverse photocatalysts such as Ru(bpy)3Cl2, tetrabutylammonium decatungstate TBADT, N‐doped carbon nanodots NCNDs, and vitamin derivatives which can partner with the Langlois reagent NaSO2CF3, CF3CO2H, and perfluoroalkyl iodides RF‐I as fluoroalkylating reagents. Also, electrocatalytic methods that make use of the cathodic reduction of CF3SO2Cl to generate CF3 radicals can achieve trifluoromethylation reactions of alkoxy‐substituted (hetero)arenes. On the other hand, thermal methodologies comprising Pd(OAc)2 catalysis and using CF3Br as trifluoromethylating source have been implemented.
