Electrooxidative B−H Functionalization of <i>nido</i>‐Carboranes

Abstract

) has been developed under electrochemical reaction conditions. In this reaction system, anodic oxidation serves as a green alternative for traditional chemical oxidants in the oxidation of nido-carboranes. No transition-metal catalyst is required and different heteroatoms bearing a lone pair are reactive in this transformation. Coupling nido-carboranes with thioethers, selenides, tellurides, N-heterocycles, phosphates, phosphines, arsenides and antimonides demonstrates high site-selectivity and efficiency. Importantly, nido-carboranes can be easily incorporated into drug motifs through this reaction protocol.
