“Complete” nuclear magnetic resonance spectrum of 4,6-diamino-3,5-dicyano-2-cyanomethylpyridine

Abstract

The structure of the molecule of 4,6-diamino-3,5-dicyano-2-cyanomethylpyridine is confirmed by the ¹³C NMR spectrum which, together with the ¹H and ¹⁵N NMR spectra (the "complete" NMR spectrum), allows almost unambiguous assignment (with the exception of the virtually coinciding paired signals of the atoms of carbon and nitrogen of the 3- and 5-CN groups). The applicability of the method of increments in the ¹³C NMR was shown in the assignment of the signals of the carbon atoms in pyridine derivatives. The ratio of the chemical shifts of the nitrogen and hydrogen atoms of the amino groups, known from the literature for aminobenzenes, was confirmed.
