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.

The first asymmetric hydrogenation of β,β-diaryl unsaturated phosphonates has been realized for synthesis of β,β-diaryl chiral phosphonates with excellent enantioselectivities (up to 99.9% ee) catalyzed by the Rh-(R,R)-f-spiroPhos complex. Furthermore, this catalyst also exhibits comparably excellent performance for β-aryl-β-alkyl unsaturated phosphonates providing the corresponding chiral phosphonates with up to 99.9% ee values. This methodology provides a straightforward access to asymmetric synthesis of chiral phosphonates.
