In the presence of 1-phenyl-5-mercaptotetrazole as a nucleophile, electrochemical oxidations of 1,2- and 1,4-dihydroxybenzenes have been investigated in aqueous solution using cyclic voltammetry and controlled-potential coulometry. The voltammetric results indicate that an electrooxidative/Michael-type sequential reaction occurs between the mercaptide anion

The antifungal effect of substituted 1-phenyl-5-mercaptotetrazoles was tested with Candida tropicalis, C. pseudotropicalis, C. mogii, Trichosporon cutaneum, Cryptococcus albidus and S. cerevisiae. Candida strains exhibited the lowest sensitivity to the compounds; the most sensitive was S. cerevisiae. The MIC values
