During UV irradiation in the presence of thiourea (or thiosemicarbazide) the para- and ortho-halogen and sulfonyl derivatives of the benzene, naphthalene, and heterocyclic series with donating substituents in the ring are converted into arylisothiuronium salts.Thermal hydrolysis and oxidation of these salts lead to the formation of the respective diaryl disulfides in the case of the para isomers and thiazoles for the ortho isomers.
