Artykuł
The application of the [Rh(acac)(CO)(PPh3)], [A], complex as a hex-1-ene hydroformylation catalyst (at 1 MPa and 353 K) produced 68% hex-2-ene and 20% aldehydes. Identified via IR in the post-reaction mixture were [Rh4(CO)12], [D], and [Rh6(CO)16], [E], carbonyls, which, applied as catalysts, produced hex-2-ene with a 70–90% yield. The presence of free triphenylphosphine changed the reaction course completely and increased the yield of aldehydes to 80% in all catalytic systems, independent of the catalyst precursor structure. The presence of amines [TBA (tribenzylamine), TFA (triphenylamine), and PhNH2 (aniline)] in reactions catalyzed by [A] and [A] + PPh3 leads to a decrease in the hex-2-ene yield and an increase in the yield of aldehydes.
