the synthesis of site‐specifically substituted phenols is challenging, and thus the development of new methods for this purpose would be highly desirable. Reported here is a protocol for palladium‐catalyzed ortho‐selective alkylation reactions of phenols with primary alcohols by a dearomatization‐rearomatization strategy, with water as the sole by‐product. Various substituted phenols and primary alcohols
苯酚是从药物到聚合物的各种工业化学品的常见前体和核心结构。但是,定点取代的苯酚的合成具有挑战性,因此非常需要为此目的开发新方法。此处报道的是通过脱芳香化-再芳香化策略,以水为唯一副产物,进行苯酚与伯醇的钯催化邻位选择性烷基化反应的方案。各种取代的苯酚和伯醇均符合标准反应条件。还研究了这种转化的详细机制。
