AI Article Synopsis
- A new strategy for selectively adding boron to aromatic esters at the para position has been developed.
- This method utilizes a modified bipyridine catalyst that enhances para-selectivity during the reaction.
- The key to this selectivity lies in the L-shaped ligand, which interacts with the oxygen in the ester group and helps control the C-H activation process.
Article Abstract
An efficient strategy for the para-selective borylation of aromatic esters is described. For achieving high para-selectivity, a new catalytic system has been developed modifying the core structure of the bipyridine. It has been proposed that the L-shaped ligand is essential to recognize the functionality of the oxygen atom of the ester carbonyl group via noncovalent interaction, which provides an unprecedented controlling factor for para-selective C-H activation/borylation.
