  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。

  precursors of chemical products, synthesis of site-specific substituted phenols is highly desirable and a significant challenge. An aerobic palladium-catalyzed site-specific synthesis of ortho-substituted phenols from cyclohexanones and primary alcohols via an oxidation/aldol/dehydration/aromatization process has been developed. Various substituted cyclohexanones and primary alcohols are successfully transformed

  由于酚作为化学产品的结构核心和前体的重要性，因此非常需要合成位点特定的取代酚，这是一个重大挑战。已经开发了一种好氧钯催化的环己酮和伯醇经氧化/羟醛/脱水/芳构化过程的邻位取代苯酚的位点特异性合成。各种取代的环己酮和伯醇已成功转化为邻位取代的酚。另外，该催化反应使用空气作为末端氧化剂并产生水作为唯一的副产物。此外，该方法还可以扩展到伯醇和仲醇之间具有高化学选择性的多羟基取代的底物。
• Method of producing high yield alditol acetals with mineral acids and surfactants

  公开（公告）日：2002-09-26

  This invention relates to a process for preparing alditol acetals, such as dibenzylidene sorbitols, monobenzylidene sorbitols, and the like, through the reaction of unsubstituted or substituted benzaldehydes with alditols (such as sorbitol, xylitol, and ribitol) in the presence of a mineral acid and at least one surfactant having at least one pendant group of 6 carbon chains in length. Such a reaction provides a cost-effective, relatively safe procedure that provides excellent high yields of alditol acetal product. Furthermore, such a specific reaction is also the best known procedure for the production of certain compounds which can be easily separated from other formed isomers. Additionally, such a procedure facilitates the production of certain asymmetric alditol acetal compounds and compositions in acceptable yields as well. Such alditol acetals are useful as nucleating and clarifying agents for polyolefin formulations and articles, as one example.
