SYNTHESIS AND PROPERTIES OF PHENYLENEBIS-1H-TETRAZOLES

Gaponik, P. N.,Karavai, V. P.,Davshko, I. E.,Degtyarik, M. M.,Bogatikov, A. N.

, p. 1274 - 1278 (2007/10/02)

Heterocyclization of m- and p-phenylenediamines with orthoformic ester and sodium azide has given phenylenebis-1H-tetrazoles.Under these conditions, o-phenylenediamine gives benzimidazole. o-, m-, and p-Phenylenebis-1H-tetrazoles were also obtained from the nitroanilines via the intermediate nitro- and aminophenyltetrazoles.The reactions of the bistetrazoles examined were basic hydrolysis, aminomethylation, and complex formation with copper salts.
