A new and readily available bidentate ligand, namely, pyrrolidine-2-phosphonic acid phenyl monoester (PPAPM), has been developed for the copper-catalyzed formation of C-N, C-O, and P-C bonds, and various N-, O-, and P-arylation products were synthesized in good to excellent yields by using the CuI/PPAPM catalyst system. Addition of the PPAPM ligand greatly increases the reactivity of the copper catalyst
已开发出一种新的且容易获得的双齿配体,即吡咯烷-2-膦酸苯基单酯(PPAPM),用于铜催化的CN,CO和PC键以及各种N-,O-和P的形成。通过使用CuI / PPAPM催化剂体系,合成了芳基化产物,收率良好。PPAPM配体的加入大大增加了铜催化剂的反应性,并且所得到的通用和有效的催化剂体系在交叉偶联反应中具有广泛和实际的应用。
