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.

The reactions of various nitrofluorobenzenes, C6HxFyNO2, with sodium methanethiolate have been studied in ethylene glycol/pyridine mixture as solvent.All the fluorine atoms, but not the nitrogroups, could be substituted by the methylthio group.The reactions have also been studied with the addition of a deactivating group, either methyl or amino, on the aromatic nucleus.Some of the methylthio groups in the products were oxidized to the corresponding sulfones.The new compounds isolated have been characterized and their spectra (IR, NMR and mass) examined.
