Enantiodifferentiation of chiral cationic cages using trapped achiral BF4– anions as chirotopic probes
Abstract
The addition of enantiopure TRISPHAT anions to chiral cationic cages of type [Co4(L)6(BF4)]7+ leads to the enantiodifferentiation of the ligands of the racemic salts and, even more effectively, of the achiral tetrafluoroborate anion trapped inside.
