A Ag-catalyzed decarboxylative fluorination reaction provides an unprecedented route to either gem-difluoroalkanes or α-fluorocarboxylic acids from malonic acid derivatives by the judicious selection of base and solvent. This reaction features the use of readily available starting materials, tunable chemoselectivity and good functional group compatibility.
