• 論文の詳細を見る

• The tautomeric behavior of 5-nitro-2-anilinopyridine and 2-anilinopyrimidine was studied. 2-(<I>N</I>-Methylanilino) and l-methyl-2-(phenylimino)-1,2-dihydro derivatives were prepared as models for the amino and imino tautomers, respectively, and their spectra were compared. The results and the assumed tautomeric equilibrium constants strongly suggest the equilibria to be favorable to the amino tautomers, the <I>K</I><SUB>t</SUB> values being considerably smaller than that of the parent 2-anilinopyridine.
