Abstract
The addition of Fe(CO)(5) to the systems with [Rh(acac)(CO)L] complexes (L = PPh3, P(OPh)(3), P(NC4H4)(3)) as catalyst precursors caused the increase of aldehydes yield in 1-hexene hydroformylation reaction (80 degrees C, 10 atm) up to 71%. The IR and H-1 NMR measurements confirm the formation of an unstable bimetallic intermediate, [(H)(PPh3)(3)Rh(mu-CO)(2)Fe(CO)(4)], cha racterized with nu(CO) at 1749 cm(-1) and hydrido signal at delta -15.8 ppm .
