Copper-mediated cross-coupling of H-phosphonates with vinyliodonium salts:: A novel very mild synthesis of 2-arylvinylphosphonates

We report a novel, very mild, highly stereoselective preparation of 2-arylvinylphosphonates at room temperature that involves the copper iodide-mediated cross-coupling of H-phosphonates with vinyliodonium tetrafluoroborates.
