A highly efficient Ir-catalyzed regioselective cage B(4)-H acylmethylation of o-carboranyl acids using sulfoxonium ylides as alkylating regents has been developed, leading to the preparation of a large class of B(4)-acylmethylated o-carboranes in good to excellent yields with a broad substrate scope under redox neutral conditions.
A highly efficient Ir-catalyzed regioselective cage B(4)-H acylmethylation of o-carboranyl acids using sulfoxonium ylides as alkylating regents has been developed, leading to the preparation of a large class of B(4)-acylmethylated o-carboranes in good to excellent yields with a broad substrate scope under redox neutral conditions. The-COOH moiety serves as the traceless directing group and controls the regioselectivity and monoselectivity.
