Peculiarities of NMR 1H and 13C Spectra of Alkyl Groups in Functionalized Linear Alkanes of the General Formula CH3(CH2)mY

Literature data of NMR 1H and 13C spectra of linear alkanes X–(CH2)n–Y (I), (where X = H; Y – 38 different substituents, including H and CH3) were considered. The new universal way of estimating the chemical shifts values of the methylene groups (δHCH2 = δHi, δCCH2 = δCi, i = 1–36) in I was proposed.

Study of the Influence of Substituent R Nature in Phenylsulfones Derivatives PhSO2R on the Chemical Shifts of Phenyl Ring Protons in NMR 1H Spectra

At the explanation of the spectra peculiarities of phenylsulfones of the general formula C6H5SO2R the arguments in favour of intramolecular influence through the space of functional groups situated in fragment R on the value of phenyl protons chemical shifts iH have been adduced.
