  9-芴基膦在有机溶剂和水中用于Pd催化的Sonogashira，suzuki和Buchwald-Hartwig偶联反应。

  摘要：

  芴的锂化/烷基化导致各种9-烷基芴（烷基= Me，Et，iPr，-Pr，-C18H25）> 95％的收率，对此进行锂化和与R2PC1的反应（R = Cy，iPr，tBu ）生成9-烷基，9-PR2-芴，它们构成了富电子且庞大的膦配体。在有机溶剂中的芳基氯化物和芳基溴化物的Sonogashira，Suzuki和Buchwald-Hartwig反应中测试了原位形成的钯-膦配合物（[Na2PdCl4] 、,盐，碱，底物）。在1-mol％的Pd催化剂下，在100-120摄氏度下，芳基氯化物的Sonogashira偶联可导致> 90％的收率。芳基氯的Suzuki偶联通常需要在100摄氏度的二恶烷中加入0.05摩尔％的Pd催化剂，以定量形成产物。为了在水中进行“绿色”交叉偶联反应，使9-乙基芴基二环己基膦在硫酸中反应，生成相应的2-磺化phospho盐。通过使用这种水溶性催化剂进行的活化芳基氯的Suzuki偶联仅需要0
