Abstract (German)

Von der aktiven Spezies [Rh(PPh3)2Cl] des bekannten Wilkinson Katalysator wurden zwei PPh3-Moleküle durch den chiralen zweizähnigen Liganden diop ersetzt. Der daraus resultierende neutrale Komplex [Rh(diop)Cl]2 bildet das Standardsystem in der enantioselektiven Hydrierung von Ketopantolacton. Auch die neu dargestellten Komplexe [Rh(diop)PPh3Cl] und [Rh(diop)PPh3I) wurden in diesem Katalysesystem ...


Translation of the abstract (English)

The Wilkinson-type catalysts [Rh(diop)(PPh3)Cl] and [Rh(diop)(PPh3)I] have been synthesised and characerised by X-ray structure analysis. The catalysts were tested in the enantioselective hydrogenation of ketopantolactone in which the iodo complex with 65ee achieved a higher enantioselectivity than the chloro complex with 55ee. The replacement of PPh3 with monodentate nitrogen ligands and the ...
