Ultrasound-Promoted Chemoselective Oxysulfonylation of Alkenes

Abstract

The ultrasound-assisted oxysulfonylation of different alkenes using sodium salts of organosulfinic acids under air atm. was described. The reaction is chemo- and regioselective and the corresponding β-ketosulfones were obtained in good yields as major products. The use of ultrasound greatly accelerated the formation of products when compared to the conventional methods. [on SciFinder(R)]
