A radical coupling reaction of DMSO with sodium arylsulfinates in air : mild utilization of DMSO as C1 resource for the synthesis of arylsulfonyl dibromomethane

A radical coupling reaction of DMSO with sodium arylsulfinates under air atmosphere to afford arylsulfonyl dibromomethane is described. This transformation provides a novel approach for the utilization of DMSO as a C-1 resource with mild temperature without the need for an anaerobic atmosphere.
