摘要
合成与表征了两类１４种烷基钴Ｓｃｈｉｆｆ碱配合物ＲＣｏ（ｃｈｅｌ）Ｌ（Ｒ＝ＣＨ_３，Ｃ_２Ｈ_５，ｎ－Ｃ_３Ｈ_７，ｎ－Ｃ_４Ｈ_９，ｉ－Ｃ_４Ｈ_９；ｃｈｅｌ＝ｓａｌｅｎ，ＳＢ；Ｌ＝Ｐｙ，γ－ｐｉｃ，ＰＰｈ_３），其中ＲＣｏ（ＳＢ）Ｌ是一类新的辅酶Ｂ_（１２）模型化合物，五配位的Ｃ_２Ｈ_５Ｃｏ（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．
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 B12model compounds. The properties of alkylcobalt complexes in solution and solid were studied. The influence factors on the stabilities of Co-C bonds of the complexes were discussed.
