title: Camphor ionic liquid: correlation between stereoselectivity and cation-anion interaction.
abstract: [structure: see text] As a halogen-free anion for an imidazolium room temperature ionic liquid, the use of a camphorsulfonate causes an increase in the number of free (naked) imidazolium cations, which produces an effective endo/exo stereoselective Diels-Alder reaction.
