Dispersion-controlled C6-selective C–H borylation of indoles
Abstract
Through DFT and NCI analysis, we designed a bulky tertiary phosphine directing group, enabling an iridium-catalyzed C6-selective borylation of indoles with a simple and commercially available ligand, 1,10-phenanthroline. The directing group has dual dispersive interactions with both phenanthroline and a Bpin group, which enhance selectivity and reactivity.
