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

report a metallaphotoredox method for the preparation of fluoroalkyl arenes based on the synergistic combination of Ir/Cu dual catalysis from boronic acids. The mild conditions allow broad functional group tolerance, including substrates containing aldehydes, free phenols, and N-Boc-protected amines. Mechanistic investigations support a process proceeding via photoredox/copper dual catalysis.
