morpholino‐induced elimination of 5‐nitrobenzisoxazole into the relevant 2‐cyano‐4‐nitrophenolate has been used as a sample reaction in order to investigate molecular properties of some room temperature ionic liquids. The kinetic study was carried out at 298 K by means of spectrophotometric measurements. Ionic liquids, which differ in both their cation and anion properties, were used as solvent systems. In particular
The introduction of new noncovalent interactions to build functional systems is of fundamental importance. We here report experimental and theoreticalevidence that anion-πinteractions can contribute to catalysis. The Kemp elimination is used as a classical tool to discover conceptually innovative catalysts for reactions with anionic transition states. For anion-π catalysis, a carboxylate base and a
