An efficient cascade process for the preparation of 2-substituted 1,3-benzothiazoles directly from 2-haloaryl isothiocyanates and O or S nucleophiles by a Cu-catalyzed, intramolecular, C–S bond formation has been developed. This cascade method is viable for the efficient syntheses of both O- and S-substituted 1,3-benzothiazoles. Furthermore, 1,3-benzothiazol-2(3H)-ones having an alkyl group allow easy
