A novel and convenient palladium‐catalyzed cross‐coupling reaction of H‐phosphonate diesters with sodiumarylsulfinates was developed via desulfitation in the presence of silver carbonate and tetra‐butylammonium chloride. This method is highly efficient and provides a rapid access to a broad spectrum of arylphosphonate diesters in good to excellent yields.
Catalyzed by palladium(II) chloride, a diverse range of arylsulfinatesodium, potassium, lithium, silver, zinc, and copper salts undergo desulfination/C–P coupling with H-phosphonates, in the presence of silver(I) carbonate as oxidant, to produce useful arylphosphonates under microwave irradiation.

halides with diaryl and dialkyl phosphines, as well as with dibutyl phosphite, is reported. This highly efficient transformation is realized through the use of copper(I) iodide as a catalyst, N,N'-dimethylethylenediamine as a ligand, and Cs(2)CO(3) as a base. A variety of sterically hindered and/or functionalized substrates were found to react under these reactionconditions to provide products in good

The first successful oxidative coupling reaction of aryl pinacol boronic esters with H-phosphonates to deliver aryl phosphorous compounds is reported herein. These reactions between aryl boronic reagents and H-phosphonates were carried out synergistically using a Pd catalyst, additive and oxidant. Without using bases and ligands, phosphorylation was accomplished in an environmentally-friendly manner
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
