Pyridines and amines have been used as modifying ligands in the hex-1-ene hydroformylation reaction catalyzed by Rh(acac)2.Aldehydes (n + iso) were obtained in 80-85 percent yield.The active form of the catalyst has been isolated as the solid HRh(CO)3.Another complex formed in the reaction of Rh(acac)2 with H2 and CO in the presence of pyridine, Rh4(CO)84, is catalytically inactive.
