An alkali metal- or alkali earth metal-containing organic compound (i) is reacted with a leaving group- and silicon- or germanium-containing compound (ii) in the presence of a nitrogen-containing aromatic heterocyclic compound. By such a method, it is possible to produce a silicon- or germanium-containing organic compound, for example, a cyclopentadienyl compound cross-linked by a silicon atom or a germanium atom, typically a cyclopentadienyl compound which is substituted with a substituted or unsubstituted silyl or germyl group, for a short time with a high yield.
一种含有碱金属或碱土金属的有机化合物(i)与含有离去基、硅或锗的化合物(ii)在含有氮杂环芳香化合物的存在下反应。通过这种方法,可以在短时间内高产率地制备含硅或锗的有机化合物,例如,通过硅原子或锗原子交联的环戊二烯基化合物,通常是被取代或未取代的硅基或锗基取代的环戊二烯基化合物。
