Tautomeric Equilibria in Solutions of 2-Phenacylbenzimidazoles

Tautomeric Equilibria in Solutions of 2-Phenacylbenzimidazoles

Detailed NMR spectral analysis of DMSO-d6 solutions of the series of substituted 2-phenacylbenzimidazoles (ketimine form, K) reveals two from three tautomeric forms. Integrals of the 1H NMR signals are used in establishing the molar ratio of tautomers. The experimental analyses are supported by quan...
