Effective Tools for the Metal-Catalyzed Regiodivergent Direct Arylations of (Hetero)arenes

Abstract

The direct functionalization of two different C-H bonds of the same organic molecule using different procedures - also called regiodivergent C-H bond functionalization - currently represents an important research topic in organic chemistry, as it demonstrates the versatility of C-H bond functionalization methodology. Over the last decade, the number of tools to control such regiodivergent C-H bond functionalizations has increased significantly. In this account, we will present the various tools that allowed us to arylate different positions of various (hetero)arenes, via a C-H bond functionalization, using palladium or ruthenium catalysis.

Keywords: C−H bond functionalization; arylation; catalysis; palladium; regiodivergence.
