摘要

Nine novel organolanthanoid (Ln= Pr and Yb) complexes of the general type [LnCp′ 2 (μ- OCHR (1) Z)] 2 (Cp′= C5H5 or CH3C5H4, R (1)= H or Me) containing exclusively chiral, oxygen-functionalized alkoxide ligands with Z (1)= CHR (2) OMe (R (2)= Me or Ph), Z (2)= COOiBu and Z (3)= CH2COOEt have been prepared and further characterized. While five (of six) Pr complexes give rise to solution 1H-NMR spectra indicative of stable (on the NMR ...
