ABSTRACT:
A water-soluble catalyst composition comprising rhodium complexes containing diphosphine ligands, wherein the diphosphine ligands present are compounds of the formula ##STR1## where R.sup.1 is selected from the group consisting of carboxylate (COO.sup.-), sulfonate (SO.sub.3.sup.-), phosphonate (PO.sub.3.sup.2-) and R.sup.2 is selected from the group consisting of a straight-chain alkylene of 1 to 8 carbon atoms, an oxygen-containing alkylene of 2 to 6 carbon atoms, cycloalkylene of 3 to 10 carbon atoms and a member of the formulae II, III, IV or V ##STR2## a, b, c, d, e, f, g, h, k and l are individually 0 to 1, where at least one of a, b, c, d, e, f, g, h, k or l has to be equal to 1, x(s) are individually 0 or 1, y is an integer of 1 to 24, R.sup.3 and R.sup.4 are individually selected from the group consisting of alkyl of 4 to 26 carbon atoms, substituted or unsubstituted aryl of 6 to 10 carbon atoms, cycloalkyl of 6 to 10 carbon atoms and benzyl and R.sup.3 can also be hydrogen and the use thereof in hydroformylations.
