AbstractA dehydrogenative fluorination method is developed to access multi‐substituted trifluoromethylalkenes starting from a variety of gem‐difluoroalkenes. The reaction proceeds with electrophilic fluorination source NFSI only and accommodates a wide range of functional groups, thus complementing the previously reported protocols. Additionally, a visible‐light‐promoted stereoinversion is revealed to enable the access to E‐isomer enriched products.
