Sulfonated 2,2'-bis (diphenylphosphinomethyl)-1,1'-binaphthalenes, process for their preparation and their use in a process for the hydroformylation of olefinically unsaturated compounds |
摘要 |
Sulfonated diphosphines of the formula <IMAGE> in which Ar is m-C6H4-SO3M, 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. |
