- Ag(I)-catalyzed synthesis of (E)-alkenyl phosphonates by oxidative coupling of H-phosphites with β-nitroolefins
-
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.
