By the preparation of β-chloro-β-perfluoroalkyl substituted acroleins, synthesized in three steps starting from benzylcyanide and ethyl perfluoroalkyl carboxylates, a versatile class of building blocks was obtained in good yields. β-Chloro-β-perfluoroalkyl substituted vinylaldehydes represent reactive C3-building blocks for preparing perfluoroalkyl substituted N-, S- and N,S-containing five and six
