Designing superacids: A computational study of protonated boratabenzenes and the gas-phase acidity of their conjugate acids is presented. Conjugate acids of boratabenzenes substituted with CN or CF(3) groups (see figure) are highly acidic species; the protonated hexacyanoboratabenzene and hexakis(trifluoromethyl)boratabenzene have computational gas-phase acidities of 250.5 and 276.8 kcal mol(-1), respectively.
