intramolecular influence

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.
