An ionic cascade insertion/cyclization reaction of thia-/selena-functionalized arylisocyanides has been successfully developed for the efficient and practical synthesis of 2-halobenzothiazole/benzoselenazole derivatives. This synthetic protocol, incorporating a halogen atom when forming the five-membered ring of benzothia/selenazoles, is different from the existing ones, where halogenation of the preformed benzothia/selenazole precursors happens. Additionally, a facile access to 2-aminobenzothiazoles is also achieved by the one-pot cascade reaction of 2-isocyanoaryl thioethers, iodine, and amines.

By using simple and readily available DMSO as a convenient and environmentally friendly source of sulfur, a practical approach for the Pd-catalyzed decarboxylative methylthiolation of 2-nitrobenzoic acids was developed. A range of substituents on the aryl group of the ortho-nitrobenzoic acid were compatible with this process.
