Abstract

On the basis of the spectral data (1H and 13C NMR, measurements of the nuclear Overhauser effect (NOE) and t1, UV spectra), the structure of tricyclic compounds formed in the condensation of substituted o-phenylenediamines with 3,4,6-trichloropyridazine, as well as two types of isomeric products of their alkylation, was established; tautomerism and protonation of the compounds obtained were studied.
