Abstract

Under the industrial reaction conditions (H2/CO = 1:1, 1.0 MPa, 70?, the hydroformylation of olefins with rhodium-phosphine complex catalyst HRh(CO)(PPh3)3 is studied by using in situ NMR techniques. The results show that the intermediate is a hydride-rhodium carbonyl complex and the proton signal with a Rh-H bond in the 1H NMR has been observed

Key words: NMR SPECTROMETRY, ALKENE, TRIPHENYLPHOSPHINE, HYDROFORMYLATION, PHOSPHORUS COMPLEX, RHODIUM COMPLEX
