    High-Pressure IR Studies on the Asymmetric Hydroformylation of Styrene Catalyzed by Rh(I)-(R,S)-BINAPHOS
    摘要:
    Rhodium-catalyzed asymmetric hydroformylation of styrene using (R,S)-BINAPHOS (1a) and its methoxy-substituted derivative 1b as chiral ligands was monitored by in situ high-pressure IR. The rate of aldehyde production is given by r(obs) = k(obs)[Rh](1.0)[styrene](0.6)[1b]P--0.1(CO)-0.9 (k(obs) is a constant under isothermal conditions). The higher catalytic activity of the Rh-1b catalyst compared with that of Rh-1a is attributed to a higher concentration of the active species, which is generated by dissociation of CO from the major resting state RhH(CO)(2)(1) (2). A rhodium carbonyl species 10, the structure of which is unknown, is suggested to be formed from the rhodium hydride RhH(CO)(2)(1) (2), especially when the rhodium. concentration is high. Complex 10 is less active for hydroformylation and is probably responsible for the loss of %ee observed at high rhodium concentrations.

    apical−equatorial chelates. The major chelate, 1eq,ap, was shown to have an equatorial phosphine and an apical phosphite. Its structure was unambiguously assigned using low-temperature 31P NMR spectroscopy with selective decoupling of aromatic hydrogens but not of the rhodium hydride, which showed a 225 Hz trans phosphite to RhH coupling. The equilibrium constant for [1eq,ap]/[1ap,eq] was determined over

    catalysts, [HRh(L−L)(CO)2] complexes (L−L = ligands 1a−g), have been studied using high-pressure NMR and IR spectroscopy. The obtained spectroscopic data show that the ligands coordinate in an equatorial−apical fashion to the rhodium center with the phosphine in apical position. Systematic variation in configuration of the stereocenters at both the ligand bridge and the phosphine moiety revealed a remarkable
