(反)-肉桂酰基二茂铁缩二硫代碳酰腙及其Cu(Ⅱ)、Zn(Ⅱ)配合物的合成与表征

Synthesis and Characterization of (E)-Cinnamoylferrocene- Dithioylcarbohydrazones and Their Cu(Ⅱ) and Zn(Ⅱ)Complexes

合成了两种未见文献报道的Schiff碱HCFM[(反 ) 肉桂酰基二茂铁 (S) 甲基二硫代碳酰腙 ]及HCFB[(反 ) 肉桂酰基二茂铁 (S) 苄基二硫代碳酰腙 ]及其铜 (Ⅱ )、锌 (Ⅱ )的六个配合物Cu(CFM) 2 ·H2 O、Cu(CFM)OAc·H2 O、Cu(CFB) 2 ·H2 O、Zn(CFM) 2 ·2H2 O、Zn(CFM)OAc·H2 O、Zn(CFB) 2 ,考察了它们的物理性质 ,并利用元素分析、IR、1HNMR谱及摩尔电导表征了它们的组成、可能结构及配位过程。实验结果表明 :这两种Schiff碱都是反式双齿配体 ,烯硫醇化失去质子后以负硫离子与过度金属离子形成共价键 。

Two Schiff base of HCFM[( E ) cinnamoylferrocene ( S ) methyldithioylcarbohydrazone] and HCFB [( E ) cinnamoylferrocene ( S ) Benzyldithioylcarbohydrazone] as well as six complexes of these schiff bases,Cu(CFM) 2·H 2O,Cu(CFM)OAc·H 2O,Cu(CFB)2·H 2O,Zn(CFM) 2·2H 2O,Zn(CFM)OAc·H 2O and Zn(CFB) 2,have been synthesized and characterized. The possible coordinating progess and complex structures are discussed. It is found that the ligands are bidentate with trans configuation coordinating to the metal ions via nitrogen and sulfer atoms after their tautomerizaation of thione to thiol and deprotonation of the thiol.
