• DABCO‐promoted Diaryl Thioether Formation by Metal‐catalyzed Coupling of Sodium Sulfinates and Aryl Iodides
  作者：Yanpeng Liu、Long Yin Lam、Jiqing Ye、Nicolas Blanchard、Cong Ma

  DOI：10.1002/adsc.202000221

  日期：2020.6.15

  A scalable catalytic synthesis method using commodity chemicals for constructing diaryl thioethers directly from sodium arylsulfinates and iodoarenes is reported in this study. In the presence of CuO or other copper salts such as Cu(OAc)2 as well as palladium catalysts, DABCO demonstrated to be essential to promote this transformation. Various iodoarenes and aryl sulfinates were examined and demonstrated

  这项研究报道了使用商品化学品直接从芳基亚磺酸钠和碘芳烃构建二芳基硫醚的可扩展催化合成方法。在CuO或其他铜盐（例如Cu（OAc）2）以及钯催化剂的存在下，DABCO被证明对促进这种转变至关重要。检查了各种碘代芳烃和芳基亚磺酸盐，证明了该方法的可行性。机理研究表明发生了自由基反应，而质谱可以观察到DABCO N-氧化物自由基。还讨论了涉及DABCO的可能的催化机理，表明亚铜（II）和DABCO协同还原亚磺酸盐是该偶联反应的关键步骤。

• Process for preparing polyarylene thioethers having high stability

  In a process for producing a polyarylene thioether having high stability by dehalogenation/sulfurization reaction of an alkali metal (M) sulfide such as sodium sulfide and a dihaloaromatic compound such as para-­dichlorobenzene in a polar organic solvent, the haloaromatic compound is used excessively in an appropriate range rather than the alkali metal sulfide and the latter stage of the reaction or all period of the reaction is conducted under a powerful stirring condition to a certain degree to obtain the polyarylene thioether wherein the concentration of -SM or -SH groups of the polymer terminal is lowered. The polyarylene thioether thus obtained suppresses the coloration in the processing with an apparatus made of ferrous material such as extruder.

  在通过碱金属（M）硫化物（如硫化钠）和二卤代芳香族化合物（如对二氯苯）在极性有机溶剂中的脱卤/硫化反应生产具有高稳定性的聚芳基硫醚的工艺中，在适当范围内过量使用卤代芳香族化合物而不是碱金属硫化物，并在一定程度的强力搅拌条件下进行反应的后期或整个反应期，以获得聚芳基硫醚，其中聚合物末端的-SM 或-SH 基团的浓度降低。 由此获得的聚芳基硫醚在使用铁质材料制成的设备（如挤压机）进行加工时可抑制着色。
