| Abstract: | Oxidation of 1-substituted 5-arylsulfanyltetrazoles with m-chloroperoxybenzoic acid and NaIO4 in the presence of RuCl3 leads to the formation of the 5-arylsulfonyltetrazoles. The microwave activation significantly accelerates the oxidation with sodium periodate. The phenylsulfonyl group in compounds obtained underwent the nucleophilic substitution when treated with ethanol, phenol, or benzimidazole in acetonitrile in the presence of NaOH. |
