Abstract:η2-Fullerene (C60 and C70) palladium optically active complexes with the axially chiral enantiomeric ligand of bithienyl series, (−)tetraMe-BITIOP], have been synthesized and investigated by 31P-{1H} NMR, electronic spectroscopy, CD spectroscopy, cyclic voltammetry and by single crystal X-ray diffraction.
Keywords:[60]fullerene  [70]fullerene  Palladium-fullerene complexes  Optical activity  Axial chirality  (&minus  )tetraMe-BITIOP  Circular dichroism  NMR electronic spectroscopy  X-ray structure  Cyclic voltammetry
