Here, a convenient and efficient method for the synthesis of polyfluorinated 3-amino-2-mercaptobenzothiazole-2(3H)-thione derivatives from the corresponding arylhydrazines and CS2, mediated by 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) in acetonitrile is described. The reaction proceeded via selective intramolecular ortho-fluorine atom substitution by the S-nucleophilic center of the carbon disulfide molecule attached at the first stage of the reaction (a tandem process). The reaction takes place under mild reaction conditions (room temperature), has an excellent yield, and involves readily available starting materials. © 2020 Elsevier B.V.
