The SN reactions of neopentyl, (1-adamantyl)methyl, and related substrates with potassium 2,4,6-tri-t-butylphenoxide gave the corresponding highly hindered ethers in moderate yields. They were neopentyl and (1-adamantyl)methyl 2,4,6-tri-t-butylphenyl ethers, and 1,3-bis(2,4,6-tri-t-butylphenoxy)-2,2-dimethylpropane. The kinetics for these reactions suggest the SN2 mechanism.
新戊基、(1-金刚烷基)甲基和相关底物与 2,4,6-三叔丁基苯酚钾的 SN 反应以中等产率得到相应的高位阻醚。它们是新戊基和(1-金刚烷基)甲基 2,4,6-三叔丁基苯基醚和 1,3-双(2,4,6-三叔丁基苯氧基)-2,2-二甲基丙烷。这些反应的动力学表明 SN2 机制。
