Abstract
Heterocyclic analogs of triphenylformazan have been synthesized: 1-(1'-benzylbenzimidazolyl)-3,5-diphenylformazan (I), 1-benzothiazolyl-3,5-diphenylformazan (II), and 1-benzoxazolyl-3,5-diphenylformazan (III). On a basis of the study of IR and UV spectra, the hypothesis has been put forward that I lacks a chelate ring while II and III have chelate rings with a weak intramolecular hydrogen bond. Ease of complex formation with many metals and a capacity for the formation of tetrazolium salts have been noted.
