Determination of the absolute configuration and optical purity of [(η5-C5H5)Fe(CO)(PPh3)COMe]; X-ray crystal structure of (R)-{(η5-C5H5)Fe(CO)(PPh3)COCH2CH2O[(R)-menthyl]}
Abstract
The enantiomeric purities of (R)-(–)-[(η5-C5H5)Fe(CO)(PPh3)COMe](1)[α]54622–288°(c 0.04, C6H6) and S-(+)-(1)[α]54622+288°(c 0.04, C6H6) are established by two independent methods and the absolute configurations assigned by an X-ray structure analysis of (R)-{(η5-C5H5)Fe(CO)(PPh3)COCH2CH2O [(R)-menthyl]}.
