Iridium‐Catalyzed Regioselective B(3)‐Alkenylation/B(3,6)‐Dialkenylation of o‐Carboranes by Direct B−H Activation

Iridium‐catalyzed formal alkyne hydroboration with cage B−H of o‐carborane has been achieved, leading to the controlled synthesis of a series of 3,6‐[trans‐(AlkCH=CH)]2‐o‐carboranes (Alk=alkyl), 3‐cis‐(ArCH=CH)‐o‐carboranes (Ar=aryl), and 3‐cis‐(ArCH=CH)‐6‐trans‐(AlkCH=CH)‐o‐carboranes in high yield...
