Palladium-catalyzed Suzuki-Miyaura coupling reactions of ethyl α-bromo-α-fluoroacetate with various structurally diverse arylboronicacids using a phosphine ligand proceeded smoothly to afford α-aryl-α-fluoroacetates in moderate to good yields. This method provides a practical and efficient route to diverse α-monofluorinated α-arylcarbonyl compounds. cross coupling - fluorinated compounds - boronic

Herein, we report the radiosynthesis of 18F-difluoromethylarenes via the assembly of three components, a boron reagent, ethyl bromofluoroacetate, and cyclotron-produced non-carrier added [18F]fluoride. The two key steps are a copper-catalysed cross-coupling reaction, and a Mn-mediated 18F-fluorodecarboxylation.
