The use of organic catalysis AcrH2 enables the direct β‐trifluoromethylation of carbonylcompounds by atom transfer radical addition reactions with broad substrate scopes under mild conditions. This operationally simple and robust protocol successfully converts a variety of β‐chloro carbonylcompounds into the corresponding α‐chloro‐β‐fluoroalkylcarbonyl products. A significant advantage of this method
