Abstract A convenient and efficient method for synthesizing β-fluorocinnamate and derivatives is reported. Palladium (II) catalysis was employed in β-F elimination and coupling reaction of phenylboronic acid and ethyl 3,3,3-trifluoropropionate with a high yield and E-selectivity. The reaction was conducted under mild conditions and could be widely adapted to boronic acid substrates. Graphical Abstract
