✦ Synopsis

Abstract

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.
