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.[1] Synthesis and reactionsRepresentative of other thiocarbamoyl chlorides, dimethylthiocarbamoyl chloride is electrophilic, serving as a source of R2NC(S)+.[2] It is analogous to dimethylcarbamoyl chloride (R2NC(O)Cl). Dimethylthiocarbamoyl chloride is prepared by chlorination of the related tetramethylthiuram disulfide: [Me2NC(S)]2S2 + 3 Cl2 → 2 Me2NC(S)Cl + 2 SCl2 Dimethylthiocarbamoyl chloride reacts with dithiocarbamates (R2NCS{{su|b=2|p=−}}) to give thiuram sulfides [R2NC(S)]2S. With methanethiolate, it gives methyl dimethyldithiocarbamate (Me2NC(S)SMe). References1. ^{{cite journal|title=Thiophenols from Phenols: 2-Naphthalenethiol|authors=Melvin S. Newman, Frederick W.
