HYDROFORMYLATION PROCESS EMPLOYING RHODIUM-BASED CATALYSTS COMPRISING LIGANDS HAVING ELECTRONEGATIVE SUBSTITUENTS

摘要

ABSTRACT OF THE DISCLOSUREThe present invention relates to novel ferrocene derivatives, i.e. thecompounds l,l'-bis[di(4-chlorophenyl)phosphino]ferrocene, 1,1'-bis[di(3-fluoro-phenyl)phosphino]ferrocene and l,l'-bis[di(4-trifluoromethylphenyl)phosphino]-ferrocene. These compounds are useful catalysts in hydroformylation reactions.
