Abstract: The first nickel-catalyzed phosphorylation of aryltrimethylammonium tetrafluoroborates with the formation of C–P bond instead of C–N has been developed. Starting from easily available and inexpensive aromatic amines, a variety of important arylphosphonates have been synthesized in moderate to excellent yields.

Herein, NiCl 2is employed as a cheap precatalyst in the formation of C(sp 2)-P bond via cross-coupling reaction of phenol derivatives and phosphine oxides/phosphites. This catalytic system allows a variety of phenols with diverse functional groups to transform into phosphates with good yields. No additional additive is used in this reaction.

The combination of black TiO2 nanoparticles (NPs) with a nickel catalyst provides a low-cost, sustainable, and reusable alternative dual catalytic system to a homogeneous counterpart (noble metals). This black TiO2-photoredox/nickel dual catalytic system has efficiently driven C-P bond formation between aryl iodides and diarylphosphine oxides under visible light, providing good to excellent yields as well as tolerating a variety of functional groups. The practical application of this semi-heterogeneous protocol has been highlighted by a sunlight experiment, a gram-scale reaction, and a reusability test.
