A mild and versatile approach for the directintroduction of ethoxycarbonyldifluoromethyl‐group to heteroarenesvia visible‐light photocatalysis has been developed. The new photoredox protocol has enabled the difluoromethylenation of heteroarenes containing a wide range of common functional groups under mild conditions.
