摘要

Abstract A new method is reported for the synthesis of alkyl aryl sulfones by alkylation of sodium arenesulfinates with unactivated alkyl chlorides using ionic liquid based on 1??butyl?? 3??methylimidazolium tetrafluoroborate (BmimBF4) mixed with water (2: 1) as reaction media. The ionic liquid can be reused and the procedure gives the sulfones in moderate yields.
