Tricarboxybenzenes were (tri-)protonated, resulting in the formation of astonishingly stable species. The different isomers are stabilized by mesomerism and hyperconjugation depending on the substitution pattern. These effects are observable by X-ray diffraction and NMR spectroscopy and also computable by NPA and NICS calculations, enabling qualitative and quantitative statements.

Mechanochemical production of an allyl potassium / calcium complex that polymerizes isoprene at room temperature. Without solvents present, the often far‐from‐equilibrium environment in a mechanochemically driven synthesis can generate high‐energy, non‐stoichiometric products not observed from the same ratio of reagents used in solution.
