INTRODUCTION
Dimethylthiocarbamoyl Chloride is an organosulfur compound, a yellow solid. It is often encountered as a yellow syrup. It is a key reagent in the synthesis of arylthiols via the Newman-Kwart rearrangement.
Manufacture
Dimethylthiocarbamoyl Chloride is prepared by chlorination of the related tetramethylthiuram disulfide: [Me2NC(S)]2S2 + 3 Cl2 → 2 Me2NC(S)Cl + 2 SCl. ) to give thiuram sulfides [R2NC(S)]2S. With methanethiolate, it gives methyl dimethyldithiocarbamate (Me2NC(S)SMe).
