Abstract
A copper(ii)-catalyzed aerobic oxidative reaction of arylhydrazines, DABCO·(SO2)2 and alkenes is reported. Diverse β-hydroxysulfones are generated in moderate to good yields through the hydroxysulfonylation of alkenes with the insertion of sulfur dioxide under mild conditions. In some cases, β-ketosulfones are produced.
