  芳基氟化物与二硫化物的铑催化取代反应：多氟苯的聚芳硫基化反应中的对位取向

  摘要：

  在催化量的 RhH(PPh3)4 和 1,2-双（二苯基膦基）苯存在下，芳族氟化物、有机二硫化物（0.5 当量）和三苯基膦（0.5 当量）在回流的氯苯中反应得到芳基硫化物产率高。由于三苯基膦捕获氟原子形成二氟化膦，二硫化物的两个有机硫基团有效地反应，并且氟化物取代基比氯化物和溴化物更容易反应。六氟苯与二芳基二硫化物反应分步得到1,4-二芳硫基-2,3,5,6-四氟苯、1,2,4,5-四芳硫基-3,6-二氟苯和六芳硫基苯；五氟苯得到1-芳硫基-2,3,5,6-四氟苯；1,2,3,4-四氟苯得到1,2-二芳硫基-3,6-二氟苯；和 1,2,4,5-四氟苯得到 1, 4-二芳硫基-2-5-二氟苯。多氟苯的聚芳硫基化反应表现出形成1,4-二氟苯的强烈趋势。

  requirement of higher reaction temperatures for an SNAr reaction between thiols and less reactive electron-poor aryl halides described in earlier reports has triggered intensive studies on the development of metal- and photo-catalyzed methods to promote this transformation. We report here that an SNAr reaction of thiols with most electron-poor aryl halides takes place at RT–60 °C under the action of

  早期报道中描述的硫醇和反应性较低的缺电子芳基卤化物之间的S N Ar 反应需要更高的反应温度，这引发了对开发金属和光催化方法以促进这种转变的深入研究。我们在此报告，在 K 2 CO 3和 DMAc的作用下，硫醇与大多数缺电子芳基卤化物在 RT–60 °C 下发生S N Ar 反应。在这种温和的条件下，碱和溶剂都起着至关重要的作用。对于对 S N不发生反应的（杂）芳基卤化物Ar反应中，鉴定出两种更强大的草酸二酰胺配体，使其Cu催化的偶联反应能够在低催化负载量下进行。这两种方法的结合为制备（杂）芳基硫醚提供了一种非常有吸引力的方法。

• Iridium and phosphine promoted C–F bond activation: the C–S cross-coupling of aryl fluorides with diaryl disulfides to synthesize thioethers
  作者：Liang Li、Hongyan Miao、Yuqiang Ding

  DOI：10.1016/j.tetlet.2015.09.133

  日期：2015.11

  Carbon fluorine bond is the strongest known single bond to carbon and proved very difficult to cleave. An iridium and phosphine promoted C-F bond activation was developed, for the first time achieving the C-S cross-coupling reaction of disulfides with aryl fluorides using iridium complex. The corresponding monoarylthiolation products were obtained at moderate to good yields. Thus, it represents a new method for the synthesis of aryl sulfides through C-F bond activation.
