摘要：
The invention relates to a process for preparing an aldehyde compound by hydroformylation of an ethylenically unsaturated organic compound, using a catalyst system which includes a Group VIII metal and a novel bidentate phosphite ligand. The bidentate phosphite ligand has a chemical structure according to formula (1), ##STR1## wherein R.sup.1 and R.sup.3 are respectively substituted or unsubstituted organic groups which may be the same or different, and wherein R.sup.2 is a substituted or unsubstituted tetravalent organic group.
