Iridium-Catalyzed Selective B(4)–H Amination of <i>o</i>-Carboranes with Anthranils
Lin‐Bao Zhang, Zuowei Xie
Abstract
We report here a catalytic selective cage B4–H amination of o-carboranes employing an Ir(III) complex as a catalyst and anthranils as aminating agents, leading to a large class of B4-aminated o-carboranes with very high yields and a broad substrate scope under mild conditions without any oxidants. In these reactions, the carboxyl group serves as a traceless directing unit to determine the site selectivity and degree of substitution.
