Iron(III) Chloride‐Mediated Regio‐ and Stereoselective Chlorosulfonylation of Alkynes and Alkenes with Sodium Sulfinates

Abstract

Abstract The atom‐economic and one‐pot regio‐ and stereoselective addition of sodium arenesulfinates to either alkynes or alkenes can be achieved with an iron(III) chloride hexahydrate [FeCl 3 ⋅6 H 2 O] catalytic system to afford β‐haloalkenyl and β‐chloroalkyl sulfones in moderate to good yields. magnified image
