Iron-catalyzed C-H Borylation of Aromatic Compounds

摘要

Boronic acids (RB(OH)2) and boronate esters (RB(OR)2) are key coupling partners in theSuzuki-Miyaura reaction.The CH borylation of aromatic hydrocarbons is one of the moststraightforward pathways to these boron compounds and typically proceeds under preciousand air-sensitive transition metal catalysts.1 We report herein the efficient CH borylationof various aromatic compounds using an air-stable iron catalyst.2
