METHOD FOR PREPARATION OF RUTHENIUM-CARBENE COMPLEX PRECURSORS AND RUTHENIUM-CARBENE COMPLEXES Russian patent published in 2017 - IPC C07F15/00 

FIELD: chemistry.

SUBSTANCE: method comprises purified ruthenium salt reaction with hydrogen halide to form an intermediate ruthenium product and ruthenium intermediate product reaction with L-type ligand, which is a cyclic olefin to form a ruthenium-carbene complex precursor. At that, the purified ruthenium salt is (NH₄)₂RuCl₅, (NH₄)₂RuCl₅⋅H₂O, polyhydrated (NH₄)₂RuCl₅ or (NH₄)₄[Ru₂OCl₁₀], and the intermediate ruthenium product comprises one or more ammonium cations and one or more halide ligands.

EFFECT: invention allows effective and less costly production of the ruthenium-carbene complex precursor, without the need for metal ruthenium or ruthenium trichloride mediation.
