Wang, Guanghui published the artcileDouble N,B-Type Bidentate Boryl Ligands Enabling a Highly Active Iridium Catalyst for C-H Borylation, Name: 1-Bromo-4-fluoro-2-methylbenzene, the main research area is crystal structure bidentate pyridinylbenzodiazaborole iridium preparation catalyst borylation aryl; mol structure bidentate pyridinylbenzodiazaborole iridium preparation catalyst borylation aryl; pyridinylaminoborane ligand bidentate iridium preparation structure catalyst borylation aromatic.
Boryl ligands hold promise in catalysis due to their very high electron-donating property. In this communication double N,B-type boryl anions were designed as bidentate ligands to promote an sp2 C-H borylation reaction. A sym. pyridine-containing tetraaminodiborane(4) compound was readily prepared as the ligand precursor that could be used, in combination with [Ir(OMe)(COD)]2, to in situ generate a highly active catalyst for a broad range of (hetero)arene substrates including highly electron-rich and/or sterically hindered ones. This work provides the 1st example of a bidentate boryl ligand in supporting homogeneous organometallic catalysis.
