(1)H- and (13)C-NMR Analysis of a Series of 1,2-Diaryl-1H-4,5-dihydroimidazoles

An analysis of the (1)H- and (13)C-NMR spectra of a series of 1,2-diaryl-1H-4,5-dihydroimidazoles and comparisons with 4,5-dihydroimidazoles having different substitution patterns are presented. The influence of different 1-aryl and 2-aryl group substituents on spectroscopic parameters of the hetero...

description An analysis of the (1)H- and (13)C-NMR spectra of a series of 1,2-diaryl-1H-4,5-dihydroimidazoles and comparisons with 4,5-dihydroimidazoles having different substitution patterns are presented. The influence of different 1-aryl and 2-aryl group substituents on spectroscopic parameters of the heterocyclic ring and on the contributions of possible mesomeric structures in the system was determined. Spectroscopic features are coherent with the presence of two conjugated systems (Ar(1)-N and Ar(2)-C=N) which compete with the delocalization characteristics of the amidine system.
