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?C, 10 atm) up to 71%. The IR and 1H NMR measurements confirm the formation of an unstable bimetallic intermediate, [(H)(PPh3)3Rh(?-CO)2Fe(CO)4], characterized with ?CO at 1749 cm-1 and hydrido signal at ? - 15.8 ppm.
