The synthesis of cobalt(III) complexes with the new linear pentadentate ligands meso- and racemic 2,6-bis(3S)-3-carboxy-4-methyl-2-azapentylpyridine (2) are described. Only one of the different possible isomers is obtained from each ligand. The structure of the complexes has been assigned on the basis of their 1H-NMR and CD spectra. The structure of the aqua-cobalt(III)-1a and the aqua-cobalt(III)-1b
Stereoselectivity in Reactions of Metal Complexes. Part X. Kinetics and stereoselectivity of the inner-sphere electron-transfer reaction between [Co(bamap)H2O]+ (bamap = 2,6-bis(3-carboxy-1,2-dimethyl-2-azapropyl)pyridine) and optically active iron(II) complexes
The kinetics of the electron-transfer reaction between racemic or opticallyactive [Co(bamap)H2O]+ and opticallyactive Fe2+ complexes of the three new pentadentate ligands bamap, alamp, and valmp has been investigated. All the reacting species show C2 symmetry. With respect to aquo-Fe2+, the reaction rate for the Fe2+ complexes is enhanced by a factor of 104 to 105, and the observed kΔΛ/kΛΛ ratio
