Nickel‐Catalyzed Cross‐Coupling of Bromodifluoromethylphosphonates with Arylboron Reagents

Abstract The nickel‐catalyzed cross‐coupling of bromodifluoromethylphosphonates with arylboron reagents was developed with a 1,10‐phenanthroline‐type ligand. In this process, functionalized and heterocycle‐containing boroxines were found to be suitable partners, and the catalytic modification of biologically active molecules, such as fenofibrate and indomethacin, was also successfully achieved. Furthermore, the gram‐scale reaction smoothly proceeded to give the desired product in a high yield. magnified image
