A simple method for the construction of propen-2-yl sulfones through cascade reactions of calcium carbide with arylsulfonylhydrazones using copper as a mediator is described. The salient features of this protocol are the use of readily available and easy-to-handle alkyne source, broad substrate scope, open-air condition, and simple operation procedure.

Selective sulfonylation and oxosulfonylation of alkenes with sulfinates have been developed via anodic oxidation in an undivided cell. The novel electrosynthetic method provided β-keto sulfones and vinyl sulfones with good to excellent yields in the absence of any transition metal catalyst and oxidants. Mechanism studies show that two different pathways involved in these two transformations.

(Het)Arylallenes undergo hydrosulfonylation under photoredox-catalyzed conditions. The reaction gives vinyl sulfones in a regio- and diastereoselective manner, employing sodium sulfinates as the sulfonyl source and eosin Y as the photocatalyst. Indol-1-yl, pyrrol-1-yl, phenyl, and naphtylallenes might be used. Aliphatic allenes are incompatible with the reaction conditions.
