The reaction of tris(trimethylsilyl)menthanethiol, HSCR3(R = SiMe3), with a group 14†; metal(II) bis(trimethylsilyl)amide, M(NR2)2(M = Ge or Pb), gives unexpected products: cis- and trans-[Ge(CH2Ph)(NR2)(µ-S)]2[a rare example of a group 14 cyclodi(metalthiane), MXX(µ-S)}2, by refluxing in PhMe]; [Pb(SCR3)(µ-SCR3)]2(the new ligand SCR3 evidently can function in both a terminal and a bridging fashion); and [Pb(NR2)(µ-SCR3)]2, the first simple prochiral group 14 metal(II) complex.
三(三甲基硅基)薄荷硫醇 HSCR3(R = SiMe3)与 14†族金属(II)双(三甲基硅基)酰胺 M(NR2)2(M = Ge 或 Pb)反应会产生意想不到的产物:顺式和反式-[Ge(CH2Ph)(NR2)(µ-S)]2[在 PhMe 中回流的第 14 组环二(偏二硅烷)MXX(µ-S)}2 的罕见实例];[Pb(SCR3)(µ-SCR3)]2(新配体 SCR3 显然既可以起末端作用,也可以起桥接作用);以及[Pb(NR2)(µ-SCR3)]2,第一个简单的手性 14 族金属(II)配合物。
