一个新铂配合物的合成、表征及反应机理的研究

Study on Synthesis, Characterization and Reaction Mechanism for a New Platinum Complex

合成了新配合物:氯化二氯二(1-二氯甲基-2-二甲基锍乙基甲基硫醚)合铂(Ⅱ)。通过元素分析及IR、1H-NMR、13C-NMR、H-HCOSY和MS分析进行了结构表征。根据产物结构推测反应机理为:氯化-3,3-二氯-二烯丙基锍在室温和乙醇钠作用下,首先发生分子间的分解、加成反应,生成一个新的硫醚,该硫醚再与铂配位,形成新的铂配合物。

A new complex, dichloro-di-(1-dichloromethyl-2-dimethyl sulfonium ethyl methyl sulfide)platinum(Ⅱ) chloride, was synthesized, and its chemical structure was characterized by elemental analysis, IR, 1H-NMR, 13C-NMR, H-HCOSY and MS spectra. The reaction mechanism proposed on the basis of the complex structure was that 3,3-dichloro-2-propenyldimethyl sulfonium chloride reacted with sodium ethoxide in ambient temperature and then formed a new sulfide, followed by complexing of the sulfide with platinum(Ⅱ).
