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

An efficient synthesis of arylphosphonates 3 is described. The method involves simple stirring of the dialkyl phosphite salts 2 with diaryliodonium salts 1 in dimethylformamide.
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.
