title: Silver(I)-Promoted Radical Sulfonylation of Allyl/Propargyl Alcohols: Efficient Synthesis of γ-Keto Sulfones.
abstract: An efficient Ag2CO3-promoted sulfonylation of allyl/propargyl alcohols with sodium sulfinates has been developed. The reaction tolerates a wide range of functional groups to deliver γ-keto sulfones in high yields (up to 93 %). Propargyl alcohols furnished trimerization product 1,3,5-triaroylbenzenes in the presence of sodium methanesulfinate under the standard conditions. A mechanism involving a sulfonyl radical was suggested.
