  摘要：

  本发明提供了一种绿色工艺，用于将大量取代的或未取代的肉桂醛或肉桂醇直接氧化成相应的烷基或芳基肉桂酸酯的一步法。本发明的过程是一种方便有效的绿色工艺，可以在常规、微波和超声波条件下，在氧化剂、催化剂和醇的存在下，直接从肉桂醛或肉桂醇制得各种芳基或烷基肉桂酸酯，可使用或不使用有机溶剂。这些酯类化合物在香料、香精和医药行业中具有极其重要的作用。尽管存在一些用于制备肉桂酸酯的现有技术，但它们都存在诸如使用昂贵的试剂和催化剂、反应条件苛刻、使用有毒化学品等缺陷。相比之下，本方法极为简单，涉及将底物与氧化剂混合均相或非均相催化剂和醇，在有机溶剂存在下或不存在的条件下，通过在室温下搅拌或回流或微波或超声波照射下反应，以得到所需产品。

  N-heterocyclic carbenes catalyze the oxidation of allylic, propargylic, and benzylic alcohols to esters with manganese(IV) oxide in excellent yields. A variety of ester derivatives can be synthesized, including protected carboxylates. This one-pot tandem oxidation represents the first organocatalytic oxidation of alcohols to esters. Saturated esters can also be accessed from aldehydes using this method

  N-杂环卡宾以极高的收率催化氧化烯丙基，炔丙基和苄基醇，使其与氧化锰（IV）形成酯。可以合成多种酯衍生物，包括被保护的羧酸盐。这种一锅式串联氧化代表了醇到酯的第一次有机催化氧化。也可以使用这种方法从醛中获得饱和酯。通过利用手性催化剂，酰基-杂偶氮中间体成为手性酰化剂，其可以使内消旋1,2-二醇脱对称。[反应：请参见文字]。

  There is provided a retardation film capable of adjusting an angle between a proceeding direction of a film and an optical axis of liquid crystal by employing an alignment layer formed of polymers including norbornene and improving thermal stability and photoreaction rate, a method for preparing the retardation film and a polarizer comprising the retardation film. The retardation film includes a substrate, an alignment layer formed on the substrate and made of polymers including norbornene, and an alignment layer fixing layer formed on the alignment layer and made of liquid crystal materials; the method for preparing a retardation film includes: forming a polymer layer by coating a substrate with a polymer solution including norbornene and drying the polymer solution, forming an alignment layer by irradiating the copolymer layer with linearly polarized ultraviolet rays in a predetermined direction relative to a proceeding direction of a film to give an orientation to the copolymer layer, forming a liquid crystal layer on the alignment layer by coating the alignment layer with a nematic liquid crystal solution and drying the nematic liquid crystal solution, and fixing the orientation of the liquid crystal layer by curing the liquid crystal layer; and the polarizer includes the retardation film and a polarizer film, both of which are stacked with each other. The retardation film has improved thermal stability and light reaction speed, and the retardation film whose optical axis has a desired orientation angle relative to a proceeding direction of the retardation film may be easily prepared through the irradiation of polarized ultraviolet rays.

  The present invention relates to a photoreactive polymer that comprises a multi-cyclic compound in a main chain, and a polymerization method thereof. Since the photoreactive polymer according to the present invention comprises a multi-cyclic compound having a high glass transition temperature as a main chain, the thermal stability is excellent, and since the mobility of the main chain is relatively high as compared to that of an additional polymer, a photoreactive group can be freely moved in the main chain of the polymer. Accordingly, it is possible to overcome a slow photoreactive rate that is considered a disadvantage of a polymer material used to prepare an alignment film for known liquid crystal display devices.

  本发明涉及一种包含多环化合物的光敏聚合物及其聚合方法。由于本发明的光敏聚合物包含具有高玻璃转变温度的多环化合物作为主链，因此具有优异的热稳定性，并且由于主链的运动性相对于附加聚合物而言较高，因此光敏基团可以在聚合物的主链中自由移动。因此，可以克服被认为是用于制备已知液晶显示器的取向膜的聚合物材料的缺点之一的缓慢光敏反应速率。
