The boron subphthalocyanine cation, B(SubPc) + , has been prepared as a salt of a weakly coordinating carborane anion, CHB 11 Me 5 Br 6 − , by a metathesis reaction of Et 3 Si(CHB 11 Me 5 Br 6 ) with B(SubPc)Cl. The separation of the cation and anion in the X‐ray structure indicates coordinative unsaturation at the boron center, and this is corroborated by DFT calculations. A strongly Lewis acidic nature for the B(SubPc) + cation is indicated by its hydrolysis to an unusual product, the di‐meso‐N‐protonated μ‐oxo dimer, [H(SubPc)B‐O‐B(SubPc)H] 2+ . © 2006 Wiley Periodicals, Inc.
