  Büchwald-Hartwig Reaction Applied to Synthesis of New Luminescent Liquid Crystal Triarylamines Derived from Isoxazoles

  摘要：

  The present work describes the synthesis and characterization of novel series of triarylamines isoxazoles (TAA) addressed to the organic photovoltaic materials. Diarylisoxazoles were synthesized by sequential [3+2] 1,3-dipolar cycloaddition reaction between arylnitrile oxides and selected arylalkenes followed by MnO2-oxidation. Isoxazoles were coupled to diarylamines by Buchwald-Hartwig reaction to afford desired compounds 6a-k. Some TAA display liquid-crystalline behaviour and UV-Vis absorption and fluorescence emission were analysed for all samples of TAA 6a-k.

  ring compounds exhibited mesomorphism. Smectic C, smectic A, and nematic phases were observed by optical microscopy and DSC analysis. The yield of these reactions varied from moderate to excellent (47–93%). The structure of the rigid core was investigated by single crystal X-ray diffraction, which confirmed the regioselectivity of the [3+2] dipolar cycloaddition reaction.

  在这项研究中，开发了一种区域选择性，简单和通用的铜（I）催化方法，用于制备基于非对称3,5-二取代异恶唑的一系列液晶。使用不同的取代的氯肟和苯基乙炔，进行了1,3-偶极环加成反应。还合成了在刚性核中包含异恶唑环和三键的第二系列。由Sonogashira交叉偶联从3-（4-溴苯基）-5-（4-（癸氧基）苯基）异恶唑制备新的液晶化合物。异恶唑环化合物的所有衍生物均表现出同构。通过光学显微镜和DSC分析观察到近晶相C，近晶相A和向列相。这些反应的产率从中度到优异（47-93％）不等。
