3-aryl-2-bromopropanoates 2a–p were prepared by reaction of ethyl acrylate with arenediazonium bromides 1a–p in the presence of CuBr (Meerwein arylation). These compounds react with selenourea to form 5-R-benzyl-2-iminoselenazolidin-4-ones 4a–p. Compounds 4a–p hydrolyze into the corresponding selenazolidin-2,4-diones.
