摘要:
Pnicogen chelate compounds which have two pnicogen-containing groups joined to one another via a xanthene-like or triptycene-like molecular skeleton and in which at least one pyrrole group is covalently bound via its nitrogen atom to each pnicogen atom form complexes with metals of transition group VIII which are useful as catalysts for the hydroformylation of olefins.

摘要:
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.
