Phenyl ring–substituent interactions in substituted acetanilides. Part II. Infrared spectra
Abstract
The i.r. spectra of a series of para-substituted acetanilides have been studied in order to correlate the C
O and N–H absorption with Hammett constants.
A separation of the resonance and inductive effects has also been attempted. The results are compared with those obtained from the chemical shifts of Me and NH protons.
