An electrochemical Reformatsky‐type reaction of bromodifluoroamides with aldehydes/ketones via electron reductive umpolung is reported, leading to the generation of a series of β‐hydroxy‐α,α‐difluoro amides in moderate to good yields. This protocol tolerated a variety of commercially available alkyl ketone, alkyl and aromatic aldehydes, featuring broad substrate scope and good functional group tolerance under transition metal‐free conditions without metal reduction reagents. Control experiment indicated that the reaction proceeded via an electron reductive umpolung pathway.
