Hydroformylation of 1-octene in the presence of cobalt alkylidynecarbonyl clusters

The hydroformylation of 1-octene in the presence of Co₃(CO)₉(-CR) (R=H, Me, Ph, CO₂Me, CO₂Et, CO₂Prⁱ, CO₂Bu^t, Cl, Br, OMe) alkylidynecarbonyl clusters, as well as triphenylphosphine derivatives of these complexes and heteronuclear Co₂Ni compounds have been studied. The nature of the catalytically active species in hydroformylation, as well as the processes of their formation and transformation during the reaction, have been established by means of IR spectroscopy. The effects of the reaction conditions, the nature of the substituent at the apical carbon atom, the electron donating phosphine substituent, and the substituent in the metal cluster framework have been discussed.Translated fromIzvestiya Akademii Nauk.
