ABSTRACT OF THE DISCLOSURE The invention relates to a process for preparing quaternary ammonium salts of di and trisulfonated triaryl- phosphines. The salts are of Formula I Image wherein Ar1, Ar2, and Ar3 are each independently an aryl; X1, X2, and X3 are each independently a sulfogroup; y1, y2, and y3 are each independently 0 or 1, provided that their sum is at least 1; A is an alkyl, hydroxyalkyl, aralkyl, or aryl having 6-25 carbon atoms; B, C, and D are straight chain or branched alkyl having 1-4 carbons; and n is a whole number of 1-3. The salts are useful as components of water-soluble catalyst systems which also contain metals, in particular noble metals, for the reaction of organic compounds in two-phase systems comprising an organic and an aqueous phase.
