Passing it on : Since every reaction at a prochiral ion must take place in close proximity to its counterion, it should be possible to transfer chiral information between the ions of an ionic liquid. Indeed, the hydrogenation of a prochiral, keto‐functionalized cation was found to proceed in the presence of ( R )‐camphorsulfonate in up to 80 % ee (see scheme).
