Simple transformation of crystalline chiral natural anions to liquid medium and their use to induce chirality

Simple transformation of crystalline chiral natural anions to liquid medium and their use to induce chirality

New chiral ionic liquids can be prepared simply by combining the tetra-n-hexyl-dimethylguanidinium cation with readily available chiral anions and used as an asymmetric inducing agent as demonstrated for catalytic Rh(II) carbenoid C-H insertion and Sharpless dihydroxylation.
