Iridium(III)-Catalyzed Regioselective B(4)-H Amination of o-Carboranes with Sufilimines

초록

Iridium(III)-catalyzed regioselective B(4)-H aminationisdeveloped from the reaction of o-carborane acidswith sulfilimines without any oxidants under mild conditions, whichleads to a wide range of B(4)-H aminated o-carboranes in good yields with a broad substrate scope. Moreover,the selective B(3,6)-diamination reaction of the o-carborane acid was achieved. The present reaction is attractivefrom a practical point of view because dibenzothiophene is quantitativelyrecovered and reused.
