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

A reaction for H–F bond insertion into α-diazo carbonylcompounds is reported. The protocol describes a simple reaction setup employing commercially available HF·pyr (Olah reagent) as the fluorine source. The method is rapid and practical, and allows access to a broad range of α-fluorinated carbonylcompounds in generally good yields.
