Aerobic Nickel-Catalyzed Hydroxysulfonylation of Alkenes Using Sodium Sulfinates

Nickel-catalyzed hydroxysulfonylation of alkenes was achieved using sodium sulfinates under air atmosphere. The procedure enabled the selective synthesis of fi-hydroxysulfones in good yields and suppressed the formation of,6-ketosulfones. On the contrary, sulfonylation of alkynes with sodium sulfonates afforded only fl-ketosulfones.
