Enantioselective Extraction of Di-O-benzoyltartrate Anion by Ion-Pair Extractant Having Binaphthyl-Unit

A lipophilic diphosphonium salt 1 having binaphthyl-type axial chirality was developed as a novel ion-pair extractant.By use of (R)-1, (-)-di-O-benzoyltartrate ((-)-DBT) was extracted more effectively than (+)-DBT.The enantioselectivity (α=D(-)
