We report herein a general one‐pot perfluoroalkylation/dehydrohalogenation protocol for the selective perfluoroalkenylation of silyl dienol ethers in their γ position. Importantly, this methodology is applicable to the synthesis of a wide range of γ‐perfluoroalkenylated enals, enones and α,β‐unsaturated amides. Various perfluoroalkenyl moieties could be efficiently introduced, with an important impact on the E/Z diatereoselectivity of the newly formed fluorinated double bond.

Abstract. We present a new metal‐free photocatalytic approach for the synthesis of difluoroalkoxylated ketones. This strategy involves the generation of alkoxyl radicals from pyridinium salts upon the activity of a catalytic electron‐donor‐acceptor (EDA) complex. This mild process tolerates several functional groups and can be scaled up to gram scale. Diverse products manipulations accounts for the versatility of the obtained fluorinated products, highlighting the synthetic usefulness of this method.
