Rh, Co, Ru and Pd complex catalyzed hydroformylation of ethylene using triphenylphosphine, triphenylarsine and triphenylstibine as ligands

The catalytic activities of the complexes of Pd, Ru, Co and Rh with PPh3, AsPh3 and SbPh3 ligands have been investigated for the hydroformylation of ethylene in as benzene solvent. All the studied metal complexes, other than that of Rh, with AsPh3 ligand were found to show better hydroformylation catalytic activity than those of their corresponding complexes with PPh3 and SbPh3 ligands.
