  膦-硼烷配合物：原位保护和配体在铑或钯催化的加氢甲酰化反应中的应用

  摘要：

  三芳基膦-硼烷络合物可直接用于1-辛烯的Rh催化加氢甲酰化反应（或1-戊烯的Pd催化加氢甲酰化反应）。温和的反应条件与使用相应的游离膦作为配体的反应提供了相似的预期醛产物收率和选择性。单或双齿PB加合物进行原位CO介导的脱保护，产生游离膦配体。结果表明，膦-硼烷络合物可以直接用于羰基化反应，而无需事先的脱保护步骤，反应结果几乎没有变化。

  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 31P1H} 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.

  A series of ruthenium o-phosphane complexes was synthesized and characterized. The reactivity of the prepared complexes was studied by using them as catalysts for the hydroformylation of 1-hexene. The activities depended on the binding mode of the phosphane and on the strength of the ruthenium-phosphane interaction. Strongly coordinated chelating [2-(dimethylamino)phenyl]-(diphenyl) phosphane and [2-(methylthio)phenyl]-(diphenyl) phosphane showed poor activity, while weakly chelated [2-(methoxy)phenyl]-(diphenyl) phosphane and non-chelating phosphanes such as [2-(methyl)phenyl]-(diphenyl) phosphane or [2-(ethyl)phenyl]-(diphenyl) phosphane led to higher activities.
