For the investigation of the barrier to rotation about the C(sp2)-C(aryl) bond in non-planar pivalophenones five derivatives were prepared and their 'H and 13C NMR spectra assigned. Methyl and bromine groups in the 3-position have opposite substituent effects on the chemical shifts of the 'H and "C
## Abstract The barrier to rotation about the C(sp^2^)C(aryl) single bond in non‐planar benzoyl compounds was investigated using __N__,__N__‐dimethyl, __N__,__N__‐tetramethylene and __N__,__N__‐diisopropyl derivatives of 2,4,6‐trimethylbenzamide and 2,6‐dimethoxybenzamide and __N__,__N__‐dimethyl
