We have developed a simple method for the oxyphosphorylation of arylalkynes to give β-keto phosphine oxides without the assistance of any transition metal. An inorganic base promoted the oxyphosphorylation and water played a synergistic role in the formation of various β-keto phosphine oxides. The reaction showed a wide structural scope and broad functional-group tolerance, and it proceeded under mild reaction conditions. This method solved the problem of metal dependence in the oxyphosphorylation of alkynes, providing a potential application in organic chemistry. Control experiments revealed the mechanism of the oxyphosphorylation and the synergistic role played by water in the radical process.

Here, we describe an application of hydroazidation in the instant activation of alkynes for achieving the oxyphosphorylation of unactivated alkynes with diarylphosphinoyl radicals under mild reaction conditions. This reaction provides a method for accessing β-ketophosphine oxides and phosphorus-containing pyrroles. (Figure presented.).

The photoredox-catalyzed phosphorylation of vinyl azides is described in this paper. The reaction proceeded smoothly using an inexpensive and easily-accessible Eosin Y as a photocatalyst under mild reaction conditions without any other oxidant, metal, or
