Synthesis and reactions

Representative 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
2
) to give thiuram sulfides [R2NC(S)]2S. With methanethiolate, it gives methyl dimethyldithiocarbamate (Me2NC(S)SMe).
