杂环苄基锡氨基硫脲席夫碱配合物的合成与表征

Synthesis and Characterization of Heterocyclic Benzyltin Thiosemicarbazide Schiff Base Complexes

二苄基二氯化锡和三苄基氯化锡分别与水杨醛缩氨基硫脲,含羟基芳香醛(酮)缩氨基硫脲的席夫碱钠盐反应,合成了10种新的有机锡配合物,其结构经1H NMR,119Sn NMR,IR和元素分析表征。结果表明,中心锡原子均为五配位杂单环结构。

Ten new organotin complexes were synthesized by the reactions of di- and tribenzyltin chloride with corresponding sodium salts of salicylaldehyde thiosemicarbazone, o-vanillin thiosemicarbazone, 2,4-dihydroxybenzaldehyde thiosemicarbazone, 2,4-dihydroxyacetophenone thiosemicarbazone and o-hydroxyacetophenon thiosemicarbazone. Their structures were characterized by ^1H NMR, ^119Sn NMR, IR and elemental analysis. The results showed that the central metal, Sn, was heterecyclic pentacoordinative.
