Anisotropy Effects of Conjugated Cyclic Systems, IV. 1H-NMR Spectra of Mesityl-Substituted 2,6-Dimethylbenzene Derivatives

The effect of very different substituents X on the chemical shift differences Δδ of the o- and p-methyl group 1H NMR signals of 4'-X-substituted 2,2',4,6,6'-pentamethylbiphenyl derivatives is +/- 0.045 ppm only.In comparison with X = H (0.47 ppm) electron attracting substitutents like X = N2+ increase Δδ values up to 0.53, X = CN and NO2 up to 0.52 ppm; electron releasing groups X = OH, NH2 reduce Δδ down to 0.45 and OCH3 to 0.44 ppm.Even in the 2-mesitylsubstituted 1,3,5,-trimethyltropylium ion (2) Δδ rises only up to 0.54 ppm.
