Procedure

Potassium bis(tris(pentafluorophenyl)borane)cyanide (827.5 mg, 0.7598 mmol) and chlorotriphenylmethane (211.8 mg, 0.7597 mmol) were placed in a 50 mL flask. The stirred solids were taken up in 10 mL of dichloromethane, added via syringe under argon counter-flow. An immediate reaction gave a deep yellow solution and a colorless solid. The solid was removed by filtration and washed (four times 4 mL) until all color was gone. The filtrate was reduced under vacuum to 4 mL, cooled to −78° C. and diluted with 10 mL of hexanes. The resulting suspension of brown oil was allowed to warm and stir. The oil solidified and then digested to a canary-yellow solid after stirring for 30 minutes. The yellow solid was isolated by filtration and dried under high vacuum. Yield, 935.3 mg, 95.20 percent.
