摘要
已有报道,含不对称配位氮的三价钴配合物在水溶液中碱催化下。
The rates of the base-catalyzed inversion (epimerization) at chiral nitrogen center of CCo(acac)2 (Me3en)TClO4 in aqueous solution have been measured at. 34. 0℃ by reversed-phase liquid chromatography. It was found that the isomerizations are all first order to [OH-] and [complex] . The forward and reverse second-order rate costants, k1 and k-1 were 0. 62 and 0. 32mol-1 · L · s-1. respectively. The rate constants of the Me3en complexes were ca. 5-9 times of those of Me-en complexes.
