¹⁸⁸ReN核配合物制备新方法研究

摘要: 提出了以丁二酰肼（SDH）作为N给予体，SnCl2作为还原剂，加入非放ReO4-，在草酸存在下，制备产率大于95％的188Re≡N核中间体化合物。并在此基础上，制得了放化纯大于90%的新型配合物188ReN–NEPTDD（2,2,9,9-四甲基-4,7-二氮-4-乙撑哌啶-1,10-二硫癸烷），该配合物具有较好的稳定性。

Abstract: 188ReNint2+ was obained easily in high yield(>95%) by using SDH（succinic dihydrazide） as a donor of nitride atom（N3-）,SnCl2•2H2O as a reducing agent and oxalic as an accelerant. Furthermore, a new compound 188ReN-NEPTDD, which was prepared with the radiochemical purity (RCP) over 90%.The compoud was highly stable.
