Procedure

A mixture of 15.0 g (25 mmol) of tris(2,6-dichlorobenzyl)sulfonium tetrafluoroborate in 250 ml of methylene chloride is stirred in a 3-necked flask at about 30° C., until a solution is obtained, and then reacted with sodium hexafluoroantimonate at RT as in Example 9c). Workup of the reaction mixture according to Example 9c) gives 12.6 g (67.4% of theory) of tris(2,6-dichlorobenzyl)sulfonium hexafluoroantimonate in the form of white crystals of melting point 216°-218° C.
