The Cover llustrates a BINOL-based catalyst activating fluoride atoms (yellow) by chelating their counter-cation (purple), with a fluorite
stone in the background.In their Concept M. T. Oliveira et al. explain how alkaline metal salts can be employed in asymmetric catalysis. Recent examples on asymmetric cation-binding catalysis show high turnover numbers and excellent enantioselectivities for different types of reactions, owing to ion-pairing interactions. This summary will certainly inspire investigation of new activation modes and open up a plethora of possibilities in asymmetric catalysis. More information can be found in the Concept by M. T. Oliveira et al. on
