PROBLEM TO BE SOLVED: To provide a method for producing bis(ethylcyclopentadienyl)ruthenium by which the extremely highly pure bis(ethylcyclopentadienyl)ruthenium can be produced at an inexpensive production cost. SOLUTION: This method for producing bis(ethylcyclopentadienyl)ruthenium comprises carrying out a hydrogenation reaction of bis(acetylcyclopentadienyl) ruthenium in the presence of a catalyst. Any one of a platinum catalyst, a palladium catalyst, a ruthenium catalyst and a Raney nickel catalyst is preferably used as the catalyst. Further, the bis(ethylcyclopentadienyl)ruthenium can be produced at a low cost by using a reaction product of the bis(cyclopentadienyl)ruthenium with acetic anhydride in the presence of a phosphoric acid catalyst, as the bis(acetylcyclopentadienyl)ruthenium. |
