Abstract

The reversible arm-off dissociation of the tripodal ligand MeC(CH2PPh2)3 in HRh(CO) [η3-MeC-(CH2PPh2)3] (1) under H2/CO (1:1) was studied by high-pressure IR and NMR spectroscopy. The formation of HRh(CO)22-MeC(CH2PPh2)3] (2) was observed, which explains the low n/i ratio observed for the hydroformylation of olefins. © 1991 American Chemical Society.
