Abstract

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.
