Chloroacetonitrile is the organic compound with the formula ClCH2CN. A colorless liquid, it is derived from acetonitrile (CH3CN) by replacement of one H with Cl. In practice, it is produced by dehydration of chloroacetamide.[1] The compound is an alkylating agent,[2] and as such is handled cautiously.
Chloroacetonitrile is also generated in situ by the reaction of acetonitrile with sulfur monochloride. A second chlorination gives dichloroacetonitrile, which undergoes cycloaddition with sulfur monochloride to give 4,5-dichloro-1,2,3-dithiazolium chloride:[3]
- Cl2CHCN + S2Cl2 → [S2NC2Cl2]Cl + HCl
