Polychloro-2-azapropenes are readily accessible via high-temperature chlorination of alkyl isocyanide dichlorides, N-alkylimidoyl chlorides, and Schiff bases1. The present review surveys the synthetically useful reactions of the lowest representative of the series, pentachloro-2-azapropene (trichloromethyl isocyanide dichloride, TMI) and shows that the ring-closure reactions of this compound can also be carried out with the higher homologous 1,3,3-trichloro-2-azapropenes 1.
