Abstract
New chiral complexes of Pd(O) containing either the bis(phosphine) (6,6'-dimethoxybiphenyl-2,2'-diyl)bis(3,5-di-tert -butylphenylphosphine) (MeO-BIPHEP, 1) or the phosphine-sulfur chelate (2,3,4,6-tetra-O-acetyl-1-{(2-diphenylphosphino)benzyl)thio) -beta-D-glucopyranose ((2-Ph2PC6H4CH2) -S-CHCH(OAc)CH(OAc)CH(OAc)CH(CH2OAc)O,2) have been prepared, and the solid-state structure of one of these, Pd(benzoquinone)(2), has been determined. These Pd(O) complexes reveal interesting solution dynamics, as shown by 2-dimensional exchange spectroscopy. For the MeO-BIPHEP derivatives, one can obtain useful structural insights based on the observed restricted rotation around the aryl(3,5-di-tert-butylphenl)P-C bonds.File | Dimensione | Formato | |
