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.
