Popis: | A series of 1-(2′-pyrimidyl)-3,5-diarylformazans was synthesized. Their structures were studied by means of IR and electronic spectroscopy, and assumptions regarding the most probable tautomeric forms of the investigated compounds were made. The ionization constants of the formazans were measured. It was found that 2,5-diphenyltetrazoles are formed instead of the expected tetrazolium salts in the reaction of 1-(2′-pyrimidyl)-3,5-diphenylformazans with N-bromosuccinimide. |
