Fig. 1: Borylation of aromatic C–H bonds.
From: Arene C–H borylation strategy enabled by a non-classical boron cluster-based electrophile

a Conventional routes to aryl boronic esters by direct arene borylation. b Cage opening of [B10H10]2– to generate a non-classical boron cluster-based electrophile. c Synthetic approach through cage opening of [B10H10]2– followed by the deconstruction of the corresponding 6-Ar-nido-B10H13 species.
