Light-promoted, copper catalyzed cage C-H arylation of o-carboranes with aryl halides has been achieved, leading to the facile synthesis of a variety of 1-Aryl-o-carboranes and o-carborane-fused cyclics. This method has the following features: (1) using o

The selective functionalization of carboranes has received increasing research interests due to their wild applications in chemistry, life, and material sciences. Among various structurally diverse carboranes, the development of selective functionalization of the commercially available o-carborane (1,2-C2B10H12) has largely focused on the two acidic C[sbnd]H bonds. By contrast, research on the activation of the other ten hydridic cage B–H vertices is relatively less explored. Of particularly challenging, the most electron-deficient nature of B(3,6)-H bonds render very few synthetic methods available for their functionalization. Herein, we develop a phosphine oxide-directed palladium-catalyzed highly B(3)–H selective arylation of o-carboranes under very mild reaction conditions in short reaction time.

A palladium-catalyzed direct C-arylation reaction of readily available cage carboranyllithium reagents with aryl halides has been developed for the first time. This method is applicable to a wide range of aryl halide substrates including aryl iodides, aryl bromides, and heteroaromatic halides.

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 examp
