2-Bromopropane → HCID 178505971, compound

Air inside a reaction vessel of the same kind as the one used in Example 13 is displaced by a nitrogen gas in a satisfactory manner. Then, 2.008 g (0.082 mole) of magnesium, 13.529 g (0.081 mole) of pentafluorobenzene, and 20 ml of diethyl ether are charged to the reaction vessel. Also, 10.873 g (0.084 mole) of isopropyl bromide is charged to the dropping funnel. Next, isopropyl bromide is dropped to the above contents with stirring under a nitrogen gas flow. After the completion of the dropping, the resulting reaction solution is subject to reaction for 2 hours at 57.0° C. with stirring. Consequently, pentafluorophenyl magnesium bromide is obtained in the form of a diethyl ether solution. A reaction yield of pentafluorophenyl magnesium bromide found in the same manner as Example 13 is 80.3 percent by mole.
