    摘要: Tertiary alkyl phenyl ethers may be induced to undergo thermal rearrangement on an alumina catalyst to afford the isomeric ortho-t-alkylphenol. Such rearrangement generally occurs under milder conditions than does the alkylation of a phenol with an olefin using the same alumina as an alkylating catalyst. The rearrangement remains regioselective even when the phenyl ring bears an alkoxy group, hence affords a good preparative route to such materials as 2-t-butyl-4-methoxyphenol.

    摘要翻译: 可以诱导叔烷基苯基醚在氧化铝催化剂上进行热重排,得到异构邻位叔烷基苯酚。 这种重排通常在比使用与烷基化催化剂相同的氧化铝的烯烃与烯烃的烷基化的温和条件下进行。 即使苯环带有烷氧基,重排仍然是区域选择性的,因此为2-叔丁基-4-甲氧基苯酚提供了良好的制备途径。
