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.

The general method for the tandem phosphination-decarboxylation-oxidation of alkynyl acids under aerobic conditions has been developed. In the presence of CuSO4·5H2O and TBHP, the reactions provide a novel access to β-ketophosphine oxides in good to excellent yields. This transformation allows the direct formation of a P-C bond and the construction of a keto group in one reaction.

A silver-catalyzed oxidative decarboxylative coupling reaction of arylpropiolic acids with H-phosphine oxides by using air as the terminal oxidant was developed. The reaction proceeds smoothly under mild conditions to give β-oxophosphine oxides in moderate to good yields. Preliminary mechanistic studies were conducted. Aerobic oxidative decarboxylative coupling of arylpropiolic acids with H-phosphine oxides is realized under silver catalysis.
