Tributylammonium TRISPHAT is the an organic salt with the formula [(C4H9)3NH]+[P(O2C6Cl4)3-]. The anion features phosphorus(V) bonded to three tetrachlorocatecholate (C6Cl4O22-) ligands. This anion can be resolved into the enantiomers which are optically stable (the picture shows the Δ enantiomer).The TRISPHAT anion has been used as a chiral shift reagent for cations. It improves the resolution of 1H NMR spectra by forming diastereomeric ion pairs.
