Polychloroalkylcarbimidic dichlorides, polychloroarylcarbimidic dichlorides, and polychloroalkylimidoyl chlorides, which are readily accessible via high-temperature chlorination of amines and amine derivatives1,2, react with sulfur at temperatures above 200°C with elimination of sulfur monochloride yielding chloro-substituted S,N-heterocyclic compounds. 1.
