Monofluorovinyl tosylate is a practical vinyl fluoride building block to couple with various arylboronic acids in the presence of a palladium catalyst. A high stereoselectivity in the synthesis of 2-aryl-1-fluoroethene derivatives was achieved. This approach is also applicable to the synthesis of 2,2-diaryl-1-fluoroethenes in good yields.
