Novel 2-(2-hydroxyphenyl) substituted imidazoles have been synthesized. A prototropic tautomerism of the 1-hydroxyimidazole derivatives has been studied. X-ray diffraction analysis and IR-spectroscopy have revealed that in the solid state the title compounds exist as the N-hydroxy tautomers. The 1H and 13C NMR spectra of the new imidazole derivatives are discussed. It has been shown that in chloroform...
A series of novel derivatives of imidazole containing a chromenyl moiety in position 2 of the ring has been synthesized.A characteristic response of the chromenyl ring H-2 proton to its environment allows the study of the prototropic tautomerism of novel 1-hydroxyimidazoles in solution using 1 H NMR spectroscopy. It has been shown that the predominance of one or another tautomer depends on...
