Irradiation of 4-(2-halobenzyl)-5-substituted-1,2,4-triazole-3-thiones under base mediated (CH3CN/2 M NaOH) condition afforded triazolo[3,4-b]-1,3(4H)-benzothiazines and desulfurized triazoles. Benzophenone sensitized photolysis of triazole-3-thiones gave desulfurized triazoles exclusively. The mechanism of the photocyclization/photodesulfurization and the involvement of singlet and triplet energy levels are discussed.

The photodesulfurization of 2,4-diaryl-1,2,4-triazole-3-thiones was discussed in the article. The triazole thiones were synthesized from the respective acid hydrazide and isothiocyanate. The structure of the compounds were confirmed by spectral and analytical data. It was concluded that thioenolization may facilitate the desulfurization.
