from benzenesulfonylchlorides and alkenes is described. Under acidic condition, a wide range of β-alkoxy sulfides were obtained in good to excellent yields, whereas under alkaline conditions, various vinyl sulfones were produced in moderate to good yields. A novel preparation of (E)-β-iodovinyl sulfones was achieved through direct difunctionalization of alkynes with benzenesulfonylchlorides and TBAI
An unprecedented three-component oxysulfenylation reaction of alkenes with sulfonyl hydrazides and alcohols has been developed in the presence of 20 mol% iodine to give a range of structurally diverse beta-alkoxy sulfides in good to excellent yields.

An unprecedented method for the synthesis of β-alkoxy sulfides via a NaI/HBr-mediated three-component oxysulfenylation reaction of alkenes with arylsulfinic acids and alcohols is reported. Furthermore, I2-promoted oxysulfenylation of alkenes using sodium arylsulfinates instead of arylsulfinic acids to synthesise various β-alkoxy sulfides is also described.
