Реферат:
The tautomeric equilibria of acylmethylpyrazines and -quinoxalines in chloroform were studied by 1H, 14N, and 17O NMR spectroscopy. It was shown that keto-enol tautomerism is realized in the acylmethylpyrazine series. Annelation leads to the development of an ylidene tautomer in the acylmethylquinoxaline series. A marked dependence of the position of the intrachelate equilibrium on the character of the solvent was observed. © 1988 Plenum Publishing Corporation.
