Abstract

Ethyl α-(diethylphosphono)acrylate (1a) and α-(diethylphosphono)acrylonitrile (1b) prepared by thermolysis of ethyl 2-diethylphosphono-2-phenylsulfinylpropionate (2a) and 2-diethylphosphono-2-phenylsulfinylpropionitrile (2b) react with various nucleophiles to generate corresponding phosphonate anions, which subsequently react with carbonyl compounds to give annelated or acyclic olefinic compounds in good yields.
