Treatment of 2, 6-dimethyl-4-methoxybenzaldehyde with MeMgI afforded two isomeric ethers,(1A and 1B), instead of the desired 1-(2, 6-dimethyl-4-methoxyphenyl) ethanol. The NMR spectra of the high-melting isomer (1B) showed the presence of hindered rotation of aromatic Me groups. The reactions and properties of these ethers and other related ethers were examined.
