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

iodide-accelerated, palladium-catalyzed C–P bond-forming reaction of aryl nonaflates is described. The protocol was optimized for the synthesis of aryl phosphine oxides and was found to be tolerant of a wide range of aryl nonaflates. The general nature of this transformation was established with coupling to other P(O)H compounds for the synthesis of aryl phosphonates and an aryl phosphinate. The straightforward
NiCl2-catalyzed P–C coupling reaction of arylhalides and various > P(O)H-compounds under MW conditions without directly added P-ligands. The reactivity of a few aryl derivatives in the Pd(OAc)2-catalyzed Hirao reaction was also studied. An induction period was observed in the reaction of bromobenzene and diphenylphosphine oxide. Finally, the less known copper(I)-promoted P–C coupling reactions were investigated

A method was developed for the nickel-catalyzed phosphonylation of arylmesylates and tosylates with H(O)PR1R2. To the best of our knowledge, this is the first example of nickel-catalyzed C–P coupling of arylmesylates and tosylates. Most of the substrates gave moderate to good yields under our catalytic system.
开发了一种方法用于镍催化芳基甲磺酸酯和甲苯磺酸酯与H(O)PR 1 R 2的膦酰化反应。据我们所知,这是甲硅烷基芳基磺酸盐和甲苯磺酸盐的镍催化C-P偶联的第一个例子。在我们的催化体系下,大多数底物的产率中等至良好。

A cation radical generated from a trivalentphosphoruscompound through single-electron transfer to an arenediazonium salt undergoes both ionic and radicalreactions. Relative ease of these reactions depends mainly on the number of phenyl ligands on the phosphorus atom.
