Stereoisomers oftrans- Dichlorocobalt(III) Complex with 1,7-Bis[(S)-2-pyrrolidinyl]-2,6-diazaheptane
摘要:
The complex trans-[CoCl2(SS-pyht)]+ (SS-pyht=1,7-bis[(S)-2-pyrrolidinyl]-2,6-diazaheptane), prepared via the HCl treatment of Λ-β-[CoCO3(SS-pyht)]+, was found to take the (R,R) configuration with regard to the secondary nitrogen centers involving the central chelate. The isomer ratio of two diastereomers (trans(R,S) and trans(R,R)) was estimated at the equilibrium in methanol; (R,S)/(R,R)=10.4±2.6.
