A novel reaction constructing C(sp2)-P bond via the silver-catalyzed polarity-matched oxidative coupling of various H-phosphites with β-alkyl nitroolefins has been achieved. The reaction was performed by using acetonitrile as the solvent and Ni(NO3)2·6H2O as the oxidant, which could restrain unwanted isomerization of β-nitroolefins and selective produce (E)-alkenyl phosphonates in up to 83% yield.

A metal-free, open-flask 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 more reactive C=C bonds toward the sulfonyl radical addition. As a result, allylic sulfones were prepared in excellent yields with a broad substrate scope under mild conditions.

Go catalytic! A highly enantioselective hydrogenation of β,β-disubstituted nitroalkenes and isomeric mixtures of nitroalkenes by using a Rh/DuanPhos catalytic system under basic conditions has furnished a convenient approach to β-chiral nitroalkanes, whic
