Abstract

In the superbasic medium dimethylsulfoxide/KOH, potassium p-fluorobenzenesulfonate (1) can be treated with PH3 [Eq. (a)], or primary or secondary phosphanes to afford water-soluble phosphanes (3) containing sulfonated aromatic groups. The trianion [P(C6H4pSO3)3] in 2 · KCl · 0.5H2O is the first in this class of compounds that could be characterized by X-ray crystallography.
