High Chemoselectivity in the Construction of Aryl Methyl Sulfones via an Unexpected C-S Bond Formation between Sulfonylhydrazides and Dimethyl Phosphite

A highly chemoselective route to aryl methyl sulfones via an unexpected C S bond formation between sulfonylhydrazides and dimethyl phosphite catalyzed by NaI under mild conditions has been established. This transformation provides an alternative and metal-free pathway to acquire various aryl methyl sulfones in good to excellent yields. Notably, dimethyl phosphite was employed as a stable and readily available alkyl source.

One-pot approach for the regioselective synthesis of β-keto sulfones based on acid-catalyzed reaction of sulfonyl chlorides with arylacetylenes and water

Reaction of sulfonyl chlorides with arylacetylenes and water in the presence of a catalytic amount of sulfonic acid in THF provided β-keto sulfones in good yields with excellent regioselectivity.
