Procedure

To a solution of 11 mg of chloro(1,5-cyclooctadiene)-rhodium(I) dimer and 0.61 mL of 4,4,5,5-tetramethyl-[1,3,2]dioxaborolane in 15 mL toluene was added dropwise 1.0 mL of 3-fluorostyrene, and stirred at room temperature for 4 hours. The reaction solution was added with water, and dried over anhydrous magnesium sulfate. The solvent was evaporated, and the resultant crude product was purified and separated by silica gel column chromatography (diethyl ether:n-hexane=1:19), to afford 311 mg of the title compound as a pale yellow oil.
