Abstract

The invention relates to a method for the hydroformylation of ethylenically unsaturated compounds, whereby at least one complex of a metal of subgroup VIII is used as the hydroformylation catalyst, having at least one compound containing phosphorus, arsenic, or antimony as a ligand. Each compound comprises two groups having a P, As, or Sb atom and at least two other heteroatoms, said groups being bound to a xanthene-type molecular structure. The invention also relates to novel compounds of this type and catalysts comprising at least one complex of a metal of subgroup VIII having at least one such compound as a ligand.
