  Palladium‐Catalyzed Suzuki–Miyaura Cross‐Coupling of Various Aryl Halides Using ortho ‐Alkyl‐Substituted Arylphosphanes and ( ortho ‐Alkylphenyl)alkylphosphanes under Microwave Heating

  摘要：

  AbstractMono‐ and dinuclear palladium(II) chloride complexes of various ortho‐alkyl‐substituted aryl‐ and alkylphosphanes were prepared. Subsequently, these were characterized by 1H NMR and 31P{1H} NMR spectroscopy, X‐ray crystallographic studies and mass spectroscopy. The palladium complexes were screened as potential catalysts for the microwave‐assisted Suzuki–Miyaura coupling reaction of several aryl halides under aerobic conditions. A preliminary study showed that excellent results can be obtained even for electron‐rich bromides and unactivated aryl chlorides with an optimized solvent, base and catalyst loading using specific phosphane ligands.

  ane)]2 were also determined. We report a systematic, solvent-dependent method to prepare palladium(II) complexes of the aryl phosphines o-methylphenyldiphenylphosphane, o-cyclohexylphenyldiphenylphosphane and o-phenylphenyldiphenylphosphane with a desired nuclearity. We demonstrated that chlorinated solvents promote the formation of dinuclear chlorine-bridged palladium complexes for all five ligands

  在各种溶剂中用膦配体邻甲基苯基二苯基膦，邻乙基苯基二苯基膦，邻异丙基苯基二苯基膦，邻环己基苯基二苯基膦和邻苯基苯基二苯基膦制备邻烷基取代的膦的氯化钯（II）配合物。配合物的结构通过1 H NMR和31 P NMR光谱及元素分析进行表征。PdCl 2（邻甲基苯基二苯基膦）2，PdCl 2（o-异丙基苯基二苯基膦）2，PdCl 2（邻环己基苯基二苯基膦）2，PdCl 2（邻苯基苯基二苯基膦）2，[PdCl 2（邻甲基苯基二苯基膦）] 2，[PdCl 2（邻乙基苯基二苯基膦）] 2和[PdCl 2（o -环己基苯基二苯基膦）] 2也被确定。我们报告了一种系统的，依赖溶剂的方法来制备芳基膦o的钯（II）配合物-甲基苯基二苯基膦，邻环己基苯基二苯基膦和邻苯基苯基二苯基膦具有所需的核。我们证明了氯化溶剂促进了所有五个配体的双核氯桥钯复合物的形成。在起始溶剂仅微溶于溶剂的其他溶剂中，配体优先形成单核钯配合物。
