Catalytic hydrophosphination is a useful technique for the synthesis of phosphines, however, the phosphine products have been little exploited as ligands in catalysis. We have selected three phosphines prepared by iron catalyzed hydrophosphination and used them as ligands in a series of cross-coupling reactions: Heck, Suzuki-Miyaura and Buchwald-Hartwig. Rather than limit the chemistry to simple cross-coupling
催化氢磷酸化是合成膦的有用技术,但是,膦产物几乎没有被用作催化中的配体。我们选择了铁催化氢磷酸化制备的三种膦,并将它们用作一系列交叉偶联反应的配体:Heck,Suzuki-Miyaura和Buchwald-Hartwig。与其将化学反应局限于几乎可以保证在这些转化中表现良好的简单交叉偶联配偶体,还探索了从电子和/或立体角度来看具有挑战性的工业相关底物,以及包含多个杂原子的底物,以实现以下目的:测量这些膦配体的真正潜力。
