Abstract

An ionic liquid based on 1-butyl-3-methylimidazolium tetrafluoroborate (BmimBF4) is used as a reusable reaction medium for the alkylation of sodium arenesulfinates with alkyl halides. This procedure is convenient, efficient and generally gives rise to the S-alkylated product with high selectivity when applied to active halides.
