  通过 Pd 催化的乙烯基磺酸衍生物和芳烃重氮盐的 Matsuda-Heck 反应生成苯乙烯磺酸盐和 -磺酰胺

  摘要：

  芳烃重氮盐与乙烯基磺酸盐和 - 磺酰胺发生 Matsuda-Heck 反应，以高到极好的收率和高到极好的选择性得到苯乙烯磺酸衍生物。通过在燃气表装置中量化氮气随时间的演变，比较了乙烯磺酸乙酯和基准烯烃丙烯酸甲酯的反应性，用于富电子和缺乏芳烃重氮盐。叔磺酰胺在 Matsuda-Heck 偶联中以高转化率反应，但需要很长的反应时间，这妨碍了通过测量氮释放来确定动力学数据。发现仲磺胺无反应性。根据这些结果，可以推导出以下反应性顺序：H2C=CHCO2Me > H2C=CHSO2OEt > H2C=CHSO2N(Me)Bn >> H2C=CHSO2NHBn。

  A first of its kind electrochemical approach for the direct synthesis of alkyl alkenesulfonates using styrenes, SO2 stock solution and alcohols was developed. The reaction features the in-situ generation of a monoalkylsulfite species with subsequent radical addition to an anodically oxidized styrene substrate. The applicability of the protocol was demonstrated with a broad scope as well as a gram-scale
