制备方法与用途

用途

3,5-二氯苯甲醚是一种醚类衍生物，可用作有机中间体。

制备

在氮气保护下，将2升反应瓶中加入1,3,5-三氯苯（254.1克，1.4摩尔）、甲醇钠（151.2克，2.8摩尔，30%溶液），升温至65～75℃并保温。通过跟踪反应检测直至完全反应为止，过滤后用400克二氯甲烷萃取，并用水洗涤至中性，干燥后除去溶剂得到粗品3,5-二氯苯甲醚。随后安装刺型分馏柱进行蒸馏，得到主馏分229.1克，收率为93%，GC纯度为92%。

  摘要：

  由于S N Ar过程，甲醇钠与HMPA中的二氯苯反应生成氯茴香醚。然后过量的MeONa通过S N 2反应使醚脱甲基，得到氯酚。用三氯苯和四氯苯可以将最初形成的氯茴香醚脱烷基化为氯酚，或者可以进一步取代生成氯二甲氧基苯；它们与过量的MeONa反应，得到氯甲氧基苯酚。在取代基的电子效应的基础上，介绍并讨论了用二，三和四氯苯的各种异构体获得的结果。

  We present the efficient synthesis of a new molecular spoked‐wheel structure (MSW‐3). Two derivatives with diameters of approximately 4 nm have been prepared. By highlighting the importance of pseudo‐high‐dilution conditions during cyclization, we were able to access the compounds on a several hundred milligram scale. In addition to the standard characterization (NMR spectroscopy, MS), we describe

  我们提出了一种新的分子辐轮结构（MSW-3）。已经制备了两种直径约4nm的衍生物。通过强调在环化过程中假高稀释条件的重要性，我们能够以几百毫克的规模使用这些化合物。除了标准表征（NMR光谱，MS）之外，我们还通过与适当的模型生色团进行比较来描述荧光MSW的光学性质的详细研究。此外，还通过光和X射线散射实验对溶液中的结构进行了全面研究。扫描隧道显微镜（STM）揭示了分子在高取向热解石墨上的二维组织，并强调了辐条轮结构。通过小角度X射线散射测量的这些分子的直径与STM获得的直径非常吻合，并且与分子建模的结果相符。这证实了辐条的刚性作用，从而产生了形状持久的纳米级扁圆形有机化合物。

  powerful catalytic system for hydroxylation of (hetero)aryl halides. A wide range of (hetero)aryl chlorides bearing either electron-donating or -withdrawing groups proceeded well at 130 °C, delivering the corresponding phenols and hydroxylated heteroarenes in good to excellent yields. When more reactive (hetero)aryl bromides and iodides were employed, the hydroxylation reactions completed at relatively
