CAAC-stabilised 9,10-diboraanthracene: an electronically and structurally flexible platform for small-molecule activation and metal complexation

Abstract

In its bent form a cyclic alkyl(amino)carbene (CAAC)-stabilised 9,10-diboraanthracene diradical enables concerted small molecule activation by the two boron centres, while in its planar form it acts as an η6-heteroarene ligand to group 6 carbonyls.
