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
C–H phosphorylation of thiazole derivatives with diarylphosphine oxides by a photoredox process in the absence of an external oxidant. The scope of thiazoles and phosphine oxides was further investigated, as was functional group tolerance. The general and operational simplicity provides a novel metal and oxidant-free alternative for the formation of heteroaryl-P bonds, and only molecular hydrogen is

The first solvent-free manganese(III) acetate-promoted reaction of benzothiazole/thiazole derivatives with organophosphorus compounds including phosphine oxides, phosphinate ester, and phosphonate diester has been efficiently developed under ball-milling conditions, providing a highly efficient and green protocol to structurally diverse C2-phosphonylated benzothiazole/thiazole derivatives with remarkable

The directphosphorylation of (benzo)thiazoles with various H-phosphine oxides was realized by using K2S2O8 as the oxidant. A series of 2-phosphoryl (benzo)thiazoles were obtained in moderate to good yields.
