摘要： 应用1H NMR技术推定了新合成的二(3-取代X基-2,4-戊二酮).N-甲基乙二胺合钴(Ⅲ)配合物:[Co (Xacac)2(Me-en)]ClO4(X=CH3、Cl、NO2)的△(R)∧(S)和△(S)∧(R)异构体的空间构型,测定了各配合物异构体手性配位氮原子上的重氢化速率常数kD值(34.0℃).结果表明,取代基X对kD值有着显著影响。

Abstract: In this paper,the steric structures of the isomers,△(R)∧(S)and △(S)∧(R),for the new synthesized bis(3-substituted X-2,4-pentanedionato)(N-methyl-ethylenediamine)cobalt(Ⅲ) complexes.[Co (Xacac)2(Me-en)]ClO4(X=CH3,Cl,NO2) were assigned,and the rate constants of deuteration(kD, 34.0℃) at the chiral nitro-gen for the complexes were measured by 1H NMR method. The experimental results showed that the kD values are remarkably affected by the substituent groups.

Key words: Bis (3-substituted X-2,4-pentane dionato)(N-methyl-ethylenediamine) cobalt (Ⅲ) complex, 1H NMR, The rate constant of deuteration
