Procedure

An aqueous solution of 8.90 g of lithium butyltriphenylborate in 100 ml of water was added to a solution of 7.24 g of dimethylphenacyloxosulfonium bromide in 100 ml of methanol, and the resultant mixture was stirred at room temperature for 30 minutes. Then, the reaction mixture was filtered, and the resultant crystal was washed with water and dried to give 10.61 g of dimethylbenzyloxosulfonium-butyltriphenylborate as a white crystal.
