ABSTRACT:
The present invention provides a novel method for simply and efficiently producing a ruthenium aromatic complex which is suitable also as an industrial method. The production method includes reacting a ruthenium aromatic complex with an aromatic compound as a ligand of the ruthenium aromatic complex, In a sealed reaction container at a reaction temperature higher than the boiling point of the aromatic compound to produce a ruthenium aromatic complex having, as a ligand, an aromatic compound having a lower boiling point.
