METHOD FOR HYDROFORMYLATION, XANTHENE-BRIDGED LIGANDS AND CATALYST COMPRISING A COMPLEX OF SAID LIGANDS

摘要

IN A PROCESS FOR THE HYDROFORMYLATION OF ETHYLENICALLY UNSATURATED COMPOUNDS, AT LEAST ONE COMPLEX OF A METAL OF TRANSITION GROUP VIII. WITH AT LEAST ONE PHOSPHORUS-, ARSENIC-OR ANTIMONY-CONTAINING COMPOUND AS LIGAND IS USED AS HYDROFORMYLATION CATALYST, WHERE THE COMPOUND USED AS LIGAND IN EACH CASE COMPRISES TWO GROUPS WHICH COMPRISE A P, AS OR SB ATOM AND AT LEAST TWO FURTHER HETERO ATOMS AND ARE BOUND TO A XANTHENE-LIKE MOLECULAR FRAMEWORK. NEW COMPOUNDS OF THIS TYPE AND CATALYSTS WHICH COMPRISE AT LEAST ONE COMPLEX OF A METAL OF TRANSITION GROUP VIII. WITH AT LEAST ONE SUCH COMPOUND AS LIGAND ARE ALSO PROVIDED.
