A solution of 2.38 g of lithium phenyltri-n-butylborate in 50 ml of acetonitrile was added to a solution of 5.00 g of bis(p-fluorophenyl)[3,3-dicyano-2-p-tolyl-2-propenyl]sulfonium (p-toluenesulfonate) in 100 ml of acetonitrile, and the resultant mixture was stirred at room temperature for 30 minutes. Then, 200 ml of water was added. The resultant precipitate of a yellow oily component was recovered, and 100 ml of dichloromethane was added. The dichloromethane layer was washed with water, dried and concentrated to give 2.09 g of bis(p-fluorophenyl)[3,3- dicyano-2-p-tolyl-2-propenyl]sulfonium-phenyltri-n-butylborate.
