Bis(2-methylallyl)(1,5-cyclooctadiene)ruthenium(II)
Bis(2-methylallyl)(1,5-cyclooctadiene)ruthenium(II) (CAS 12289-94-0; linear formula Ru(methylallyl)2(COD); molecular weight 319.45) is an organoruthenium(II) complex bearing two 2-methylallyl ligands and a chelating 1,5-cyclooctadiene ligand. Supplied as a defined-stoichiometry coordination compound, it is used principally as a versatile ruthenium precatalyst and precursor in homogeneous catalysis, including asymmetric and cross-coupling chemistry and the in situ generation of active ruthenium species for organic synthesis.

Ruthenium precatalyst for homogeneous catalysis
Acts as a well-defined ruthenium(II) source that combines with chiral or achiral ligands to generate active catalysts in situ. It is associated with precatalyst platforms for asymmetric and cross-coupling catalysis.
Asymmetric hydrogenation catalyst synthesis
Serves as a convenient precursor for preparing chiral ruthenium complexes used in enantioselective transformations. The labile methylallyl and cyclooctadiene ligands are readily displaced to install the desired ligand set.
Catalyst and ligand research
Used in academic and industrial laboratories to study ruthenium-mediated reactivity and to develop new catalytic systems. The defined structure supports reproducible catalyst preparation and screening.
Precursor to supported and molecular ruthenium species
Functions as a clean organometallic source of ruthenium for the controlled generation of molecular and nanostructured ruthenium materials in synthetic and materials chemistry.
