Abstract:
The present invention relates to a method for efficiently producing a ruthenium complex (1 A ) by reacting a dinuclear ruthenium complex (2 A ) with a compound (3 A ) in the presence of a primary alcohol and a base. The ruthenium complex (1 A ) can also be efficiently produced by treating a dinuclear ruthenium complex (4 A ) with a primary alcohol and a base. (In the formulas, solid lines, triple lines, broken lines, C, H, N, OP, Ru, X, AH and R 1  to R 12  have the meanings defined in the specification.)

Claim (Index 7):
