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.
用MeMgI处理2,6-二甲基-
4-甲氧基苯甲醛,得到两种异构的醚(1A和1B),而不是所需的1-(2,6-二甲基-4-
甲氧基苯基)
乙醇。高熔点异构体(1B)的NMR光谱表明存在芳族Me基团旋转受阻的情况。检查了这些醚和其他相关醚的反应和性质。
