The synthesis of aryl phosphonates via nickel and palladium-catalyzed cross-coupling of aryl fluorosulfonates and phosphites is described. The products were obtained in good to excellent yields under mild conditions with broad functional group compatibility, employing either Pd(OAc)2 and DPEPhos or the readily available NiCl2(dme) and Xantphos as catalytic systems. Noteworthily, the present C(sp2)?P bond formation method could be applied to the direct conversion of phenols to the corresponding aryl phosphonates in one pot via reaction of phenols with SO2F2 and subsequent palladium-catalyzed cross-coupling.

A visible-light-induced metal-free catalytic system was developed for the synthesis of arylphosphonates starting from arylhydrazines and trialkylphosphites. By using the inexpensive eosin B as catalyst, sub-stoichiometric amounts of DABCO, and ambient air as oxidant, diverse arylphosphonates were obtained under visible-light irradiation. Notably, this catalytic system is suitable for gram-scale reaction by utilizing sunlight as an illumination source.

A novel and convenient palladium-catalyzed cross-coupling reaction of H-phosphonate diesters with sodium arylsulfinates 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.
