Graphical Abstract

Thumbnail image of graphical abstract

Measure for measure: Several measures indicate that carborane acids of the type H(CHB11R5X6) (see scheme, green R, red X, gray H, pink B) for R=H, Cl and X=Cl, Br, I are the strongest pure Brønsted acids. Based on NMR and IR spectroscopy, H(CHB11Cl11) can lay claim to be the strongest isolable acid presently known.
