  通过 NHC 催化的 [3 + 3] 烯醛与 2-取代萘醌环化合成功能化二氢香豆素

  摘要：

  据报道，α,β-不饱和醛与 2-取代的 1,4-萘醌的 [3 + 3] 环化可以轻松合成由 N-杂环卡宾 (NHC) 催化的功能化二氢香豆素。最初形成的 NHC-homoenolates 经历了有效的迈克尔 - 异构化 - 内酯化级联以提供产品。对机制的初步研究揭示了 α,β-不饱和酰基唑中间体中间体的同烯醇化物途径。此外，使用手性 NHC，所需产物的产率高达 49%，比价为 99:1。

  The present invention relates to polycarbonate having repeat units derived from tert-butylhydroquinone (TBHQ). It has herein been found that polycarbonate having repeat units derived from TBHQ has superior properties as compared to polycarbonate having repeat units derived from other dihydroxy (hydroquinone-type) compounds. In one embodiment the present invention provides a polycarbonate having repeat units derived from tert-butylhydroquinone. The polycarbonate has a Mw (PC) of at least 9,000 g/mol.

  本发明涉及具有源自叔丁基对甲酚（TBHQ）的重复单元的聚碳酸酯。已经发现，与源自其他二羟基（对甲酚型）化合物的重复单元的聚碳酸酯相比，具有源自TBHQ的重复单元的聚碳酸酯具有优越的性能。在一种实施例中，本发明提供了一种具有源自叔丁基对甲酚的重复单元的聚碳酸酯。该聚碳酸酯的分子量（Mw（PC））至少为9,000克/摩尔。

  Polycarbonates containing low or undetectable levels of Fries rearrangement product may be prepared by the melt reaction of a dihydroxy aromatic compound such as bisphenol A with an ester-substituted diaryl carbonate such as the diaryl carbonate of methyl salicylate, bis-methyl salicyl carbonate. Low levels of Fries product are obtained as the combined result of a highly effective catalyst system which suppresses the Fries reaction and the use of lower melt polymerization temperatures relative to temperatures required for the analogous polymerization reaction using diphenyl carbonate.

  可通过二羟基芳香族化合物（如双酚 A）与酯取代的二芳基碳酸酯（如水杨酸甲酯的二芳基碳酸酯，即双甲基水杨基碳酸酯）的熔融反应，制备含较少或检测不到的弗里斯重排产物的聚碳酸酯。与使用碳酸二苯酯进行类似聚合反应所需的温度相比，使用高效的催化剂系统抑制弗里斯反应，并使用较低的熔融聚合温度，从而获得低水平的弗里斯产物。
