摘要：
Sulfonated diphosphines of the formula ##STR1## in which Ar is m-C.sub.6 H.sub.4 --SO.sub.3 M, M is hydrogen, ammonium, a monovalent metal, or the chemical equivalent of a polyvalent metal; Ph is phenyl; the m's are individually 1 or 2, and the n's are individually 0, 1, or 2. A method of their preparation and the hydroformylation of olefins and olefinically unsaturated compounds using these compounds as a constituent of water-soluble catalyst systems are also disclosed.
