Silver-Catalyzed Oxyphosphorylation of Unactivated Alkynes

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.).

Iron-Catalyzed and Air-Mediated C(sp3)?H Phosphorylation of 1,3-Dicarbonyl Compounds Involving C?C Bond Cleavage

A C(sp3)?H phosphorylation has been achieved via the iron-catalyzed cross-coupling reactions between 1,3-dicarbonyl compounds and P(O)?H compounds involving C?C bond cleavages with air as the oxidant. This transformation provides a straightforward way to construct C(sp3)?P bonds, leading to the formation of β-ketophosphine oxides in up to 93% yield with good functional group tolerance. (Figure presented.).

Base-Promoted Direct Oxyphosphorylation of Alkynes with H-Phosphine Oxides in the Presence of Water

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.
