Abstract
Abstract The synthesis of the 2,3-bisphosphite derivatives of phenyl 4,6- O -benzylidene-β-D-glucopyranoside leads to new chelating ligands. Their rhodium(I) and platinum(II) complexes have been tested as catalysts for the asymmetric hydroformylation of vinyl acetate, allyl acetate and p -methoxystyrene. Good regioselectivity (>90% branched product), but an enantioselectivity of only ≤36% ee were found under mild reaction conditions (25–40°C, 40–70 bar syngas).
