LIGANDS FOR PNICOGEN CHELATE COMPLEXES WITH A METAL OF SUBGROUP VIII AND USE OF THE COMPLEXES AS CATALYSTS FOR HYDROFORMYLATION, CARBONYLATION, HYDROCYANATION OR HYDROGENATION

摘要

The present invention relates to a kind of two together with base phosphorus family element chelate, it includes phosphorus family element atom, each other the bookbinding molecular skeleton triptycene similar or identical by xanthene. Airtight petite person's pyrrole group is bonded via its nitrogen-atoms with each phosphorus category atom covalence. The present invention also relates to a kind of catalyst metals of complicated composition to have at least one phosphorus family element compound as ligand from subgroup VIII, and is related to making the formylated method of hydrogenation of olefins.
