Abstract:
We have developed a highly efficient synthetic route to β-ketosulfones via AgNO3 catalyzed oxysulfonylation of alkenes using thiophenols in the presence of air (O2) and K2S2O8 as eco-friendly oxidants. Thiophenols have been used as sulfonylation precursors for the first time in a dioxygen activation based radical process. Moreover, the protocol also offers a new and convenient method for the synthesis of β-hydroxysulfides at room temperature without the use of any initiator.

Alkynes to Aldehydes and Ketones: Hydroboration-Oxidation
One of the convenient methods for the preparation of aldehydes and ketones is via hydration of alkynes. Hydroboration-oxidation of alkynes is an indirect hydration reaction in which an alkyne is treated with borane followed by oxidation with alkaline peroxide to form an enol that rapidly converts into an aldehyde or a ketone. Terminal alkynes form aldehydes, whereas internal alkynes give ketones as the final product.
