Infrared and Raman spectroscopic studies of the amino-imino tautomerism in 2-substituted 4,4-pentamethylene-5-amino-4H-imidazole derivatives-II

Abstract

In continuation of previous work, nine 2-substituted 4,4-pentamethylene-5-amino-4H-imidazole derivatives and 2-pyridyl-5,5(4.4)-pentamethylene-4(5)-imidazolone have been studied by i.r. and Raman spectroscopy. The amino-imino tautomerism of the amino-4H-imidazoles has been studied. Other possible tautomeric forms in some compounds are also discussed. © 1985.
