Abstract (en)

[origin: WO9616923A1] Process for preparing an aldehyde compound by hydroformylation of an ethylenically unsaturated organic compound in the presence of a catalyst system comprising of a multidentate phosphorous ligand and a Group 8-10 metal, wherein the multidentate phosphorus amide ligand consists essentially of a multivalent bridging organic group connected to at least two trivalent phosphorus-containing groups of formulas (A) and (B) provided that at least one group of formula (B) is present, wherein R is hydrogen, an organic group, or -SO2R<1>, wherein R<1> is a C1-12 organic group, and wherein remaining free bonds of said trivalent phosphorus groups are linked to a mono- or divalent organic group.
