N2  - N.m.r, data for 14 &#945;,&#946;,&#946;-trimethylstyrenes are given. The aromatic ring shields the &#946;-methyl group cis to it relative to the &#946;-methyl group trans to it. The magnitude of this relative shielding is greatest with ortho-substituted benzene rings. The cisoid homoallylic coupling constants in &#945;,&#946;,&#946;-trimethylstyrenes (and indeed in all examples available from the literature) are smaller than the transoid homoallylic coupling constants.
