Treatment of MAr2 [Ar- = C̄6H3(NMe2)2-2,6 and M = Ge (1) or Sn (2)] with silicontetrachloride, or 2 with SiCl3Me, under mild conditions in diethyl ether afforded in good yields the appropriate silylgermane or -stannane M(Ar)2Cl(SiCl3) [M = Ge (3), Sn (4)] and Sn(Ar)2Cl(SiCl2Me) (5). The X-ray structures of 3 and 5 show that while in 3 there is no very close Ge···N contact (the molecule having germanium
MAR的治疗2 [氩- = C 6 H ^ 3(NME 2)2 -2,6和M =葛(1)或Sn(2)]与四氯化硅,或2用的SiCl 3 Me中,在二温和的条件下醚以良好的产率提供合适的甲硅烷基锗烷或-锡烷烷M(Ar)2 Cl(SiCl 3)[M = Ge(3),Sn(4)]和Sn(Ar)2 Cl(SiCl 2 Me)(5)。3和5的X射线结构表明,在3中没有非常紧密的Ge···N接触(在扭曲的四面体环境中具有锗的分子),5在锡原子周围具有扭曲的金字塔结构,顶端有Cl和N原子。3和4在C 6 D 6中的溶液显示前者是稳定的,而后者则缓慢分解,在产物中产生β-锡和Sn(Ar)2 Cl 2。的解决方案5显示了平衡的存在2 +的SiCl 3我⇆ 5,和在CDCl 3,得到的Sn(Ar)的混合物2氯(CDCL 2)。
