title: Efficient NMR enantiodifferentiation of chiral quats with BINPHAT anion.
abstract: Hexacoordinated phosphorus BINPHAT anion is an efficient NMR chiral shift agent for quaternary ammonium cations (quats) leading to large separations (DeltaDeltadelta up to 0.29 ppm) of the proton signals of the enantiomers. [reaction: see text]
