Selective synthesis of 1,3-di- and 1,3,5-trisubstituted tetrazolium salts by tert-butylation of tetrazole, 1- and 5-monosubstituted tetrazoles, isomerization of 1,3-disubstituted salts to 1,4-salts

Tetrazole and its 1- and 5-monosubstituted derivatives are found to react with tert-butyl alcohol in 72% perchloric acid media, yielding selectively 1,3-di- and 1,3,5-trisubstituted tetrazolium salts. 1,3-Disubstituted salts are slowly converted under the same conditions into the corresponding 1,4-disubstituted salts. This transformation may be used for selective synthesis of the latter.
