The Suzuki−Miyaura cross-coupling of aryl phosphates using Ni(PCy3)2Cl2 as an inexpensive, bench-stable catalyst is described. Broad substrate scope and high efficiency are demonstrated by the syntheses of more than 40 biaryls and by constructing complex organic molecules. The poor reactivity of aryl phosphates relative to aryl halides is successfully employed to construct polyarenes by selective cross-coupling
描述了使用Ni(PCy 3)2 Cl 2作为廉价,稳定的催化剂对芳基磷酸酯进行的Suzuki-Miyaura交叉偶联。超过40个联芳基的合成以及构建复杂的有机分子证明了广泛的底物范围和高效率。通过使用Pd和Ni催化剂进行选择性交叉偶联,成功地将磷酸芳基酯相对于芳基卤化物的不良反应性用于构建聚芳烃。
