Iridium-Catalyzed Cyclative Indenylation and Dienylation through Sequential B(4)-C Bond Formation, Cyclization, and Elimination from o-Carboranes and Propargyl Alcohols
Described herein is the first iridium-catalyzed cyclative indenylation through sequential B(4)-C and intramolecular C-C bond formation from o-carboranes and propargyl alcohols, leading to the formation of B(4)-indenylated o-carboranes with excellent regioselectivity via direct B-H activation. Moreover, the iridium-catalyzed regioselective 1,3-dienylation has been accessed through sequential B-H activation, dehydration, and decarboxylation, producing B(4)-dienylated o-carboranes.
