The first nickel-catalyzed phosphinylation of C–S bonds forming C–P bonds is developed. The reaction can proceed readily with the simple Ni(cod)2 at a loading down to 0.1 mol% at the 10 mmol scale. Various aryl sulfur compounds, i.e. sulfides, sulfoxides and sulfones all couple with P(O)–H compounds to produce the corresponding organophosphorus compounds, which provides an efficient new method for the construction of C–P bonds.

of phosphine oxides to the corresponding phosphines represents the most straightforward method to prepare these valuable reagents. However, existing methods to reduce phosphine oxides suffer from inadequate chemoselectivity due to the strength of the P=O bond and/or poor atom economy. Herein, we report the discovery of the most powerful chemoselective reductant for this transformation to date, 1,3

diarylphosphine oxide compounds via a Ni-catalyzed cross-coupling of arylchlorides with R2P(O)H has been developed. Notably, this process exhibits the following very attractive features: (i) the process is simpler and operates under mild reaction conditions; (ii) the process is generally cheaper in part because the more accessible arylchloride is used to form the C–P bond; (iii) the process avoids the need

developed for photocatalytic P(O)–C(sp2) coupling of (hetero)aryl halides with H-phosphine oxides or H-phosphites under the irradiation of visible light or sunlight. The thioxanthen-9-one/nickel dual catalysis mediates this phosphonylation to give arylphosphine oxides and arylphosphonates in moderate to excellent yields. This transformation is widely tolerant to a range of functional groups and proceeds

Ni-catalyzed C–P bond formation was achieved using aromatic esters as unconventional aryl sources. The key to success was the use of a thiophene-based diphosphine ligand (dcypt). Several aromatic esters including heteroaromatics can be coupled with phosphine oxides and phosphates, providing aryl phosphorus compounds. The synthetic utility of the method was demonstrated by application of the present
