| Abstract: | Trivalent group-9 metal catalysts with a cyclopentadienyl-type ligand (CpMIII; M=Co, Rh, Ir, Cp=cyclopentadienyl) have been widely used for directed C-H functionalizations, albeit that their application to challenging C(sp(3))-H functionalizations suffers from the limitations of the available directing groups. In this report, we describe directed C(sp(3))-H amidation reactions of simple amide substrates with a variety of substituents. The combination of an electron-deficient (CpRh)-Rh-E catalyst (Cp-E=1,3-bis(ethoxycarbonyl)-substituted Cp) and an electron-deficient 2-pyridone ligand is essential for high reactivity. |
