Thio-substituted 2-pyridylferrocenes [CpFe{CH(X)(CHN)}] (X = SOTol, ; SMe, ) were prepared from [CpFe(CHR)] (R = SOTol, ; 2-CHN, ) in moderate yields. The reactions of and with [PtCl(DMSO)] yielded the binuclear N, S chelated complexes [CpFe{CH(X)(CHN)}-(к-N,S)-PtCl] (X= SOTol, , SMe, ), while the reaction of with Hg(OAc)/LiCl led to cyclomercuration with generation of [CpFe{CH(SMe)(CHN)(HgCl)}], . The crystal structures of ·CHCl and were determined. The structure of showed a weak intramolecular Fe…Pt interaction and several weak intermolecular interactions involving all Cl atoms. Weak intermolecular interactions between Hg and S atoms in the cyclomercurated led to a tetrameric structure involving a HgS ring.
硫代取代的2-吡啶基二茂铁[CpFe{CH(X)(CHN)}]（X = SOTol， ；SMe， ）由[CpFe(CHR)]（R = SOTol， ；2-CHN， ）以中等产率制备。 和 与[PtCl(DMSO)]的反应生成了双核N，S螯合配合物[CpFe{CH(X)(CHN)}-(к-N,S)-PtCl]（X = SOTol， ，SMe， ），而 与Hg(OAc)/LiCl的反应导致环汞化，生成[CpFe{CH(SMe)(CHN)(HgCl)}]， 。测定了 ·CHCl和 的晶体结构。 的结构显示出弱的分子内Fe…Pt相互作用以及涉及所有Cl原子的几个弱分子间相互作用。环汞化产物中Hg和S原子之间的弱分子间相互作用导致形成包含HgS环的四聚体结构。
