Abstract

We report here an unprecedented Fe/Cu synergistically catalyzed deesterificative or deamidative oxyphosphorylation of unsaturated carboxylates or amides with H-phosphonates. The valuable β-ketophosphonates were obtained along with chemoselective cleavage of Csp2–C(CO) or Csp–C(CO) bonds in good yields under oxygen atmosphere with a wide substrate scope.
