| 摘要 |
The present invention is a preparation method of the bis(alkylcyclopentadienyl)ruthenium by reacting a ruthenium compound, an alkylcyclopentadiene and a reducing agent, wherein the ruthenium compound, the alkylcyclopentadiene, and the reducing agent are reacted in the presence of a base. It is preferable that at least one of ammonia, amines, ammonium compounds, hydroxides, aniline, nitroaniline, aminophenol, aminodiphenyl, piperidine, Grignard reagents, alkali metals, alkoxides, phenyl lithium, methyl lithium, n-butyryl lithium, lithium aluminium hydride, and sodium amide is added as a base to the reaction system and the ruthenium compound, the alkylcyclopentadiene, and the reducing agent are reacted.
