The reaction of α-nitroolefins with triethyl or diethyl phosphite was studied and structural assignment of the products was made by spectroscopic analyses. Ethyl α,β-unsaturated α-nitrocarboxylates (IV) and 1-nitroalkenes (V) reacted with triethyl phosphite to afford ethyl β-diethoxyphosphinyl-α,β-unsaturated-carboxylates (IX) and 2-diethoxyphosphinyl-1-alkenes (X), respectively. Compound (IV) reacted
