Our search for strong and neutral but non-fluorinated XB catalysts led us to consider ortho-carborane-based systems. Dicarba-closo-dodecaboranes (called "carboranes" in the following) are neutral icosahedral 3D-aromatic borohydride clusters with two adjacent carbon atoms, which are comparable to benzene in their stability. The electron-withdrawing property of the carborane framework has led to its use as substitute for pentafluorophenyl groups in the design of Lewis superacids. Additionally, carboranes can be further substituted in their borohydride backbones, making them remarkably versatile and interesting building blocks for supramolecular chemistry. Pioneering work by Han, Fourmigué, Jeon, and coworkers has demonstrated that C-iodinated (or -chalcogenated) orthocarboranes coordinate halides in the solid state, and a few further applications in crystal engineering have appeared. To the best of our knowledge, however, there is currently no data on solutionphase binding.
