聚合体[{(2-吡啶)-(SiMe3)C}SbCl](无穷大)和含红油二苯乙烯(Sb=C)(Sb=C)是由[{(2-吡啶)(SiMe3)(2)C}(2)SbCl]消除Me3SiCl而形成的,在Tmeda的存在下与过量的Et2Zn反应,得到了具有三配位金属中心的宝石有机二锌手性笼状四聚体[Zn{C(SiMe3)(2-吡啶)}](4)[(Tmeda)Et-(Cl)]和[(Tmeda)Et2Zn]。
Treatment of both polymeric [{(2-pyridyl)-(SiMe3)C}SbCl](infinity) and the implied stibene (Sb=C) containing red oil, formed as a result of Me3SiCl elimination from [{(2-pyridyl)(SiMe3)(2)C}(2)SbCl], with excess Et2Zn in the presence of tmeda results in the geminal organodizinc chiral cage tetramer [Zn{C(SiMe3)(2-pyridyl)}](4) possessing three-coordinate metal centers, [(tmeda)Et-(Cl)Zn] and [(tmeda)Et2Zn].
