Abstract

Novel dinuclear and water-soluble rhodium complexes, well suited as hydroformylation catalysts, as are aqueous solutions thereof, have the general formula: ##STR1## in which R and R', which are identical or different, are each a substituted or unsubstituted hydrocarbon radical, with the proviso that R and R' may together form a single divalent radical, TAPS is a sulfonated triarylphosphine ligand, and L is a carbonyl (CO) or a TAPS ligand.
