Directed <i>ortho</i> C–H borylation catalyzed using Cp*Rh(<scp>iii</scp>)–NHC complexes

Abstract

Cp*Rh(NHC) complexes with bulky chiral bidentate NHC-carboxylate ligands were efficiently synthesized and fully characterized including solid-state structures. These unprecedented rhodium(iii) complexes demonstrated high selectivity in pyridine-directed ortho-C-H borylation of arenes under mild conditions.
