| Summary: | Заглавие с экрана The paper dwells on the 1H and 13C spectra of the N-aryl- and N-arylalkylureas. The effects of the aryland arylalkyl- substituents on the chemical shifts are mutually compared, as well as correlated with the corresponding effects for methylureas. Correlations between methanetriyl group's carbon Δδ's and steric factors are discussed briefly. The neighboring group influence on aromatic carbon's chemical shifts has proven to be insignificant. Comparative analysis of the 1H spectra allowed us to describe the differences between effects of various substituents on the amino proton shieldings. |
