Boryl ligands play a very important role in catalysis because of their very high electron-donating property. In this paper, NNB-type boryl anions were designed as tridentate ligands to promote aryl C-H borylation. In combination with [IrCl(COD)]₂, they 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 a new NNB-type tridentate boryl ligand to support homogeneous organometallic catalysis.
硼基配体由于其非常高的给电子性能，在催化中起着非常重要的作用。在本文中，我们设计了 NNB 型硼基阴离子作为三齿配体，以促进芳基 C-H 硼化反应。与[IrCl(COD)]₂结合，它们为广泛的（杂）芳基底物生成了一种高活性的催化剂，包括高富电子和/或空间位阻的底物。这项工作提供了一种新的 NNB 型三齿硼基配体，以支持均相金属有机催化。
