Abstract Oxidation of substituted triaylformazanes by potassium permanganate in a twophase organic solvent-water system in the presence of catalytic amounts of tetrabutylammonium bromide gives the corresponding tetrazolium salts, which are interphase transfer catalysts in oxidation, alkylation, and esterification. From distribution coefficient data it is concluded that 2,3,5-triphenyltetrazolium chloride has less catalytic activity than 2,5-diphenyl-3-(m-nitrophenyl)-tetrazolium bromide.
