Participants

Reaction Steps

1.53 mL (0.0123 mole) of C6F5Br was put in toluene in 50 omL flask. Then, 7.67 mL (0.0123 mole) of n-butyl lithium was taken with syringe and, added dropwisely in dry ice acetone bath at −78° C., and agitated for 2 hours to obtain C6F5Li. 0.64 g (0.002 mole) of Cl2B(C6F4)BCl2 was dissolved in 40 mL of toluene, added slowly to the agitating flask at −78° C. with syringe, and the reaction was performed continuously for 12 hours by elevating the temperature to the room temperature. The remaining solvent was removed under vacuum to produce salts of (Li+)2[(C6F5)3B—C6F4—B[(C6F5)3]2−.
