Method for producing dialdehydes and or ethylenically unsaturated monoaldehydes by hydroformylating ethylenically unsaturated compounds

摘要

The invention relates to a method for producing dialdehydes and/or ethylenically unsaturated monoaldehydes by reacting at least one compound with at least two ethylenically unsaturated double bonds with carbon monoxide and hydrogen in the presence of a hydroformylating catalyst with at least one complex of a metal of subgroup VIII. The subgroup comprises at least pnicogen chelate ligands.
