Abstract
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.
