The allene carbopalladation process can be realized with various vinylic or aromatic derivatives, in the presence of sodium benzenesulphinate, and allows the preparation of the entitled sulphones.
protocol was developed for the preparation of allylic sulfones through direct condensation of sodium arylsulfinates and β,β-disubstituted nitroalkenes. The key step of this process was the Lewis base-promoted equilibrium between nitroalkenes and allylic nitro compounds. Through this process, the readily available conjugated nitroalkenes can be easily converted into allylic nitro compounds, which contain

allylation viaelectrochemical promoted Ni-catalyzed reductive carbon–carbon bond formation. Readily available (hetero)aryl chlorides with a variety of allylic sulfones are used as electrophiles in this electroreductive coupling. This Ni-catalyzed modular approach displays generally good functional group tolerance and broad substrate scope. This reaction allows a series of allyliccompounds to be created
