1,1,2,2‐Tetrafluoroethyl‐containing compounds are valuable structures due to their unique physicochemical properties, which have increasing potential application in drug discovery. However, synthetic methods for preparing such compounds are rare. Herein, we report the first use of 1,1,2,2‐tetrafluoroethanesulfonyl chloride to introduce the HCF2CF2 group into organic molecules via a three‐component, radical tetrafluoroethyl‐heteroarylation of alkenes with readily available quinoxalin‐2(1
