The low-cost cobalt(II) catalyst has been used for the first time to achieve P(O)-radical-mediated bisfunctionalization of alkenes with diarylphosphine oxide and peroxides. This simple process is performed under mild conditions to afford a wide variety of phosphonation-peroxidation products in a one-pot manner. Computational studies are carried out to provide a theoretical support for the P(O)-radical-involved bisfunctionalization of alkenes. (Figure presented.).
Visible-Light-Promoted Aerobic Oxyphosphorylation of α-Diazoesters with H-Phosphine Oxides

A visible-light-promoted aerobic oxyphosphorylation of α-diazoesters and H-phosphine oxides has been developed. Using air as the oxygen source, the reaction proceeded smoothly at room temperature under blue-light irradiation. The α-diazoesters, molecular oxygen, and H-phosphine oxides are conveniently incorporated into a C-O-P(O) unit in one step. The preliminary mechanistic studies indicated that a light-triggered radical process is involved. The developed strategy shows the unrevealed reactivity of diazo compounds with H-phosphine oxides and has potential value in synthetic applications.
Mn(III)-mediated phosphinoylation of aldehyde hydrazones: Direct “one-pot” synthesis of α-iminophosphine oxides from aldehydes

A “one-pot” strategy for the straightforward Mn(III)-mediated phosphinoylation of aldehyde hydrazones with diphenylphosphine oxide to furnish α-iminophosphine oxides is described. This mild and practical method allows the direct use of aldehydes as substrates in one pot to generate the hydrazones, which are then engaged “in situ” by the phosphorus reagent in the presence of Mn(OAc)3 oxidant. Thus, the requisite isolation of the hydrazones is not needed in this operation. Conducted mechanistic experiments implicate a pathway involving phosphorus-centered radicals.
Palladium-Catalyzed Olefination of N-Tosylhydrazones as β-Diazo Phosphonate Precursors with Arylhalides

An efficient palladium-catalyzed olefination of N-tosylhydrazones as β-diazo phosphonate precursors with aryl halides has been developed. 2,2-Disubstituted vinylphosphonates bearing versatile functional groups were easily accessed in moderate to excellent
