A solution of 4-bromo-2-fluorobenzonitrile (4.92 g, 0.0246 mol), vinyltributyltin (0.78 g, 0.246 mol), and tetrakistriphenylphosphine (0.67 g, 0.58 mmol) in 250 mL of toluene was refluxed under nitrogen overnight. The solvent was evaporated and the residue was flash chromatographed on silica gel with heptane:CH2Cl2 (1:1) to pure CH2Cl2. A colourless oil was obtained that crystallised. Yield: 3.0 g (82%).
