Aromatic Polyhedral Hydroxyborates: Bridging Boron Oxides and Boron Hydrides

Abstract

No explosion, but per-B-hydroxylation occurs if the icosahedral boron hydrides [closo-B12H12]2− (see picture), [closo-CB11H12]−, or closo-1,12-(CH2OH)2-1,12-C2B10H10 are refluxed in 30 % hydrogen peroxide. Thus, the three isoelectronic species [closo-B12(OH)12]2−, [closo-1-H-1-CB11(OH)11]−, and closo-1,12-H2-1,12-C2B10(OH)10 were obtained. ○=BH, ○=BOH.
