Sodium hexafluoroantimonate → HCID 19877071, compound

Participants

Reaction Steps

A mixture of 7.0 g (15.2 mmol) of di-(4-chlorobenzyl)-phenylsulfonium tetrafluoroborate and 25 ml of methylene chloride is dissolved under N2 in a 100 ml round-bottomed flask to give a clear solution and the solution is cooled to 0°-5° C. 5.9 g (22.8 mmol) of sodium hexafluoroantimonate are added at this temperature and the mixture is stirred for about 3 h. The reaction mixture is filtered and the filtrate is freed from the solvent on a rotary evaporator. 50 ml of deionized water are now added to the residue and the product is crystallized out. It is left to crystallize at 0°-5° C. for 1-2 h. The crystals now obtained by filtration are washed with water and dried under a high vacuum at RT overnight. 8.26 g of di-(4-chlorobenzyl)-benzylsulfonium hexafluoroantimonate are obtained as white crystals of melting point 75°-77° C.
