Versatile Utility of Cp∗Co(III) Catalysts in C-H Amination under Inner-and Outer-sphere Pathway

Abstract

This Account describes the recent advances in our research program toward the development of cobalt-catalyzed C-H amidation reactions. In particular, synthetic versatilities of obtainable amino products shown to be achieved on the basis of two distinctive mechanistic scaffolds; inner-and outer-sphere pathways. It highlights our approaches to transit the modes C-N bond formation by introduction of bidentate LX-Type ligands into Cp∗Co(III) precursors, thereby broadly expanding the scope of amination reactions. 1 Introduction 2 Cp∗Co-Catalyzed Inner-sphere C-H Amidation 3 Cp∗Co-Catalyzed Outer-sphere C-H Amidation 3.1 C(sp2)-N Bond Formation 3.2 C(sp3)-N Bond Formation 4 Conclusion. © 2022 Georg Thieme Verlag.
