Reactions were carried out using Ullmann–Goldberg-type condensation with (S)-N-methyl-2-carboxylate as the ligand, and N-arylated products were obtained with moderate to good yields. The structures of the synthesized compounds were confirmed based on analytical and spectral data.enUllmann reaction; Goldberg reaction; N-arylation; 1, 2, 5-thiadiazolidine 1, 1-dioxides; aryl halide.Article
