  • Difluorocarbene transfer is mostly limited to reactions that utilize its intrinsic electrophilicity. Now, a controllable palladium-catalysed difluorocarbene transfer reaction is reported that involves nucleophilic and electrophilic palladium difluorocarbene species. The selective reactions between arylboronic acids and the difluorocarbene precursor BrCF2PO(OEt)2 give four different products—difluoromethylated and tetrafluoroethylated arenes and their corresponding fluoroalkylated ketones.

  • Chlorodifluoromethane (ClCF2H), an inexpensive and abundant industrial raw material, represents an ideal and straightforward reagent for introducing the difluoromethyl group. However, efficient approaches for activation of the typically inert ClCF2H are limited. Now, ClCF2H is employed via a difluorocarbene pathway for palladium-catalysed difluoromethylation of arylboronic acids with broad substrate scope.
