Versuchsvorschrift
A complicated synthesis of β-ethoxyacrylonitrile (I) by a plurality of steps has been described, which entails the tranposition of the sodium salt of β-hydroxyacrylic acid ethyl ester with ethanol in the presence of HCl to form β,β-diethoxypropionic acid ethyl ester, the preparation of the amide by reaction with ammonia, and further dehydration with phosphorus pentoxide, β-ethoxyacrylonitrile (I) being formed as a by-product (S. M. McElvain and R. L. Clark, J. Amer. Chem. Soc., 69, (1947) 2657).
