Directed ortho C–H borylation catalyzed using Cp*Rh(iii)–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.
