Comparative Catalytic Activity of Group 9 [Cp*M-III] Complexes: Cobalt-Catalyzed C-H Amidation of Arenes with Dioxazolones as Amidating Reagents

Abstract

A procedure for the [Cp*Co-III]-catalyzed direct C-H amidation of arenes with dioxazolone has been developed. This reaction proceeds under straightforward and mild conditions with a broad range of substrates, including anilides. A comparative study on the catalytic activity of Group 9 [{Cp*MCl2}(2)] complexes revealed the unique efficiency of the cobalt catalyst.
