regioselective synthesis of double difluoromethylated allylic products from easily accessible β,γ-unsaturatedcarboxylicacids and difluoromethylation reagents under visible-light photocatalysis is reported. This transformation tolerates various bromodifluoroacetates and fluorinated phosphonates, providing access to various difluoromethylated allylic products in 54–93% yield with 80:20 to 99:1 Z/E, which
