Abstract
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.Keywords
