Trimesitylmethylphosphonium cation. Supramolecular stereocontrol and simple enantiomerization mechanism determination.
Stereocontrol over the propeller isomerism of trimesitylmethylphosphonium cation was achieved through an ion pairing with chiral hexacoordinated phosphate anions; the asymmetric ion pairing allowed also a most simple experimental proof of the nature of the enantiomerization pathway in solution (two-ring flip).
