A new and readily available bidentate ligand, namely, pyrrolidine-2-phosphonicacidphenylmonoester (PPAPM), has been developed for the copper-catalyzedformation 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

We have developed a general, efficient, and inexpensive catalyst system for arylation of amines by using 10 mol % of CuI as the copper source, 20 mol % of diphenyl pyrrolidine-2-phosphonate (DPP) as the ligand, K3PO4 as the base, and DMF containing 2% water (v/v) as the solvent.
我们已通过使用10%(摩尔)的CuI作为铜源,20摩尔%二苯基吡咯烷-2-膦酸酯(DPP)作为配体的,K开发用于胺的芳基化的一般,有效和廉价的催化剂体系3 PO 4作为碱,以及含有2%水(v / v)作为溶剂的DMF。
