Protonation of the polyhedral anion [closo-B10H10]2– under superacidic conditions apparently generates an electrophilic intermediate, [B10H13]+, that forms 6-R-nido-B10H13 (R = aryl, alkyl, triflate) derivatives by electrophilic aromatic substitution, C–H bond activation, or ion-pair collapse, respectively. The proposed mechanism of formation of the 6-R-nido-B10H13 derivatives via the boranocation
