  Reusable Pd nanoparticles immobilized on functional ionic liquid co-polymerized with styrene for Suzuki reactions in water–ethanol solution

  摘要：

  Co-polymer of 3-(2,3-dihydroxypropyl)-1-vinylimidazolium chloride and styrene was synthesized and used as a support of Pd nanoparticles. The Pd@poly-Sty-co-diOH-Cl catalyst can efficiently catalyze Suzuki reactions for a wide range of aryl iodides and bromides with 0.05 mol % Pd at 70 degrees C in water-ethanol solution under air, and the catalyst can be recycled and reused for several times without significant loss of activity.

  10 mA in an undivided cell setup by utilizing CH3CN as a solvent and LiClO4 as an electrolyte at room temperature. Notably, the present strategy enabled the formation of sulfenylphenanthrenes and sulfenyl spiro cyclohexa[4.5]trienones in 70%–95% yield. Scale-up synthesis, mechanistic studies, and cyclic voltammetry have also been carried out.

  在这里，我们提出了以邻炔基联苯和二芳基二硫化物为原料，电化学诱导合成 9-硫基芳基菲和 3'-硫基芳基螺环己[4.5]三烯酮。该方法是通过在室温下使用CH 3 CN作为溶剂和LiClO 4作为电解质在未分割的电池装置中进行10mA的恒流电解来完成的。值得注意的是，本策略能够以 70%–95% 的产率形成硫基菲和硫基螺环己[4.5]三烯酮。还进行了放大合成、机理研究和循环伏安法。
