Due to the chemoselective dehalogenation by SmI_2, the additionof α-halomethylsulfones to carbonyl compounds afforded β-hy-droxysulfones. Those reactions with α-bromomethylsulfonesgave the products in moderate to good yields. The SmI_2-mediat-ed addition of gem-dihalomethylsulfones to ketones also afford-ed α-halo-β-hydroxysulfones in moderate yields.
