摘要： 合成与表征了两类14种烷基钴Schiff碱配合物RCo(chel)L(R=CH3,C2H5,n-C3H7,n-C4H9,i-C4H9;chel=salen,SB;L=Py,γ-pic,PPh3),其中RCo(SB)L是一类新的辅酶B12模型化合物,五配位的C2H5Co(SB)也是首次报道。研究了在固态和溶液中配合物的性质,并讨论了影响配合物中Co─C键稳定性的因素。

Abstract: Two series of alkylcobalt Schiff base complexes RCo(chel)L(where R=CH3,C2H5, n-C3H7, n-C4H9, i-C4H9; chel=salen and SB; L=py,γ-pic, PPH3)were synthesized and characterized in which RCo(SB)Land five-coordinate C2H5Co(SB) are new coenzyme B12 model compounds. The properties of alkylcobalt complexes in solution and solid were studied. The influence factors on the stabilities of Co-Cbonds of the complexes were discussed.

Key words: Coenzyme B12 model compounds, Co-C bond, Alkylcobalt complexes, Schiff base
