A synergistic Cu/Fe-catalyzed aerobic oxyphosphorylation of alkynes or alkynyl carboxylic acids with H-phosphonate is disclosed. The useful β-ketophosphonate products were obtained in good yields under oxygen atmosphere in a novel way. This reaction exhibits a wide substrate scope, and the mechanistic experiments indicate that a radical mechanism forms both C-P and C═O bonds simultaneously. This mechanism contrasts existing aerobic difunctionalization of alkynes.
公开了一种铜/铁协同催化的炔烃或炔基羧酸与H-膦酸酯的需氧氧膦酰化反应。在氧气氛围下,以一种新颖的方式以良好的产率得到了有用的β-酮膦酸酯产物。该反应具有广泛的底物范围,机理实验表明自由基机理同时形成C-P键和C═O键。这种机理与现有的炔烃需氧双官能化反应不同。
