Abstract

Calculations based on density functional methods are carried out to investigate the effects of a variety of substituents (NMe2, OMe, Me, F, H, Cl, CN, NO2) on the Mulliken charges (QM) for Ca and N atoms of N-(4-Substituted benzylidene)-1-phenylmethanamine oxide using Hammett’s MSP and Taft’s DSP equations. The MSP and DSP correlations give normal substituent effect at Ca and N atom sites. This can be attributed to extended pi-polarization, which predominates over the localized pi-polarization.

 

Keywords:  Correlation analysis; Hammett’s and Taft’s equations; Nitrone compounds; pi-polarization; Mulliken charges; DFT calculation.
