The anionic complex [NBu₄][Pd(DMSO)Cl₃], which can be synthesized on a gram scale in a single step starting from commercially available starting materials, has been shown to be an active catalyst in the Mizoroki–Heck reaction of aryl halides. We present two new catalytic applications of this complex: the base-free oxidative Heck reaction and the reductive homodimerization of aryl halides. This complex outperformed other palladium salts. In the latter reaction, the catalyst loading could be reduced to 0.01 mol %. The scope of the reactions has been explored, demonstrating the potential of the anionic palladium complex in these catalytic transformations.

阴离子“无配位”钯配合物催化的氧化和还原交叉偶联反应

阴离子络合物[NBu ₄ ] [Pd（DMSO）Cl ₃ ]可以从商业上可得的原料开始以克为单位一步合成，已显示出是Mizoroki-Heck反应的活性催化剂。芳基卤化物。我们介绍了该复合物的两个新的催化应用：无碱氧化Heck反应和芳基卤化物的还原均二聚。该络合物的性能优于其他钯盐。在后一反应中，催化剂负载量可降低至0.01mol％。已经探索了反应的范围，证明了阴离子钯络合物在这些催化转化中的潜力。
