Direct B–H Activation of Carborane Clusters via Synergistic LMCT and HAT Photocatalysis

The functionalization of B-H bonds in carboranes represents a significant goal in boron cluster chemistry, holding great potential for the construction of advanced functional materials and bioactive molecules. However, the inherent inertness of the B-H bond, characterized by a high bond dissociation energy (about 100 kcal/mol), presents a formidable challenge. Conventional strategies typically rely on transition-metal-mediated activation or prefunctionalization of the boron vertices, which may suffer from poor atom- and step-economy and frequently require harsh reaction conditions and noble catalysts. Herein, we report a photoinduced iron-catalyzed platform for the direct and redox-neutral B-H…
