Abstract
The present invention provides a method for inexpensively producing di-μ-chloro-bis[chloro(η-1-isopropyl-4-methylbenzene)ruthenium (II)] complex used as a catalyst raw material for a hydrogenation or metathesis polymerization reaction at a high yield. In the present invention, the above-described problem can be solved by reacting ruthenium chloride or a hydrate thereof with γ-terpinene in a solvent. In particular, by using an alcohol having a boiling point of 100° C. or higher as a solvent, the yield of the above-described complex can be increased.
