Nickel‐Catalyzed Cross‐Coupling Reactions of <i>o</i>‐Carboranyl with Aryl Iodides: Facile Synthesis of 1‐Aryl‐<i>o</i>‐Carboranes and 1,2‐Diaryl‐<i>o</i>‐Carboranes

Abstract

A nickel-catalyzed arylation at the carbon center of o-carborane cages has been developed, thus leading to the preparation of a series of 1-aryl-o-carboranes and 1,2-diaryl-o-carboranes in high yields upon isolation. This method represents the first example of transition metal catalyzed C,C'-diarylation by cross-coupling reactions of o-carboranyl with aryl iodides.
