摘要：
4,5-Dichloro-1,2-dithiole-3-thione 2 undergoes a 1,3-dipolar cycloaddition with DMAD to give stable aliphatic thioacyl chloride 3, which is highly reactive towards nucleophiles such as omicron-substituted amines to give benzimidazole, benzoxazole and benzothiazole derivatives of 1,3-dithioles 9.
