Air inside the reaction vessel as in Example 1 was replaced with a nitrogen gas in a satisfactory manner. Then, 180 ml of dibutyl ether solution containing 0.354 mol of ethyl magnesium bromide as hydrocarbon magnesium halide was charged to the reaction vessel. Further, 0.365 mol of bromopentafluorobenzene was charged to the dropping funnel as fluoroarylhalide. Next, after dropping the bromopentafluorobenzene in the dropping funnel over 120 minutes at 25° C., the content of the reaction vessel was stirred for thirty minutes at 25° C., thereby obtaining pentafluorophenyl magnesium bromide as the fluoroaryl magnesium halide, obtained as a colorless dibutyl ether solution.
