Ethyl 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.
