摘要: 5种氨基酸的Schiff碱及2种半卡巴腙分别与双-(茂基二羰基铁)二氯化锡反应制得7种新的含有Fe—Sn—Fe三核金属有机配合物,中心锡原子为五配位.合成反应产率较好,产品纯度也高.该类配合物的母体为双环氮杂锡氧烷.产物结构均经红外、核磁、质谱及元素分析确证.研究发现,氨基酸中α-碳上的取代基对铁上的茂环有影响.

关键词: Schiff碱, 有机锡, 双环氮杂锡氧烷, 多核金属有机配合物

Abstract: Seven novel Fe-Sn-Fe containing multinuclearorganometallic complexes were Prepared by the reaction of bis(cyclopentadienyldicarbinylferro)tin dichloride with Schiff Base or semicarbazones.All of the complexes wre characterized by elementary analysis,IR,NMRand MS, respectively.The central metal, Sn, was five coordinative and the complexes were the bicycloazastannoxides as that reported previously.The substituted group on the carbon atom of the amino acid influenced the chemical shift of Hat the ferrocenyl in the complexes formed.Mass spectra show that Sn-Fe bond is first cleavaged and gives similar fragments as reported previously.

Key words: Schiff base, Organotin, Bicycloazastannoxide, Multinuclearorganometallic complexes
