A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 37366-09-9, Name is Dichloro(benzene)ruthenium(II) dimer, molecular formula is C12H12Cl4Ru2.

Applications of transition metal complexes containing 3,3?- bis(diphenylphosphinoamine)-2,2?-bipyridine ligand to transfer hydrogenation of ketones
Hydrogen transfer reduction processes are attracting increasing interest from synthetic chemists in view of their operational simplicity. 3,3?-bis(diphenylphosphinoamine)-2,2?-bipyridine, (Ph 2PNH)2C10H6N2, was prepared through a single step reaction of 3,3?-diamino-2,2?- bipyridine with diphenylchlorophosphine. Reaction of (Ph2PNH) 2C10H6N2 with [Ru(eta6- benzene)(mu-Cl)Cl]2, [Rh(mu-Cl)(cod)]2 or [Ir(eta5-C5Me5)(mu-Cl)Cl]2 gave a range of new bridged dinuclear complexes [C10H6N 2{NHPPh2Ru(eta6-benzene)Cl2} 2], 1, [C10H6N2{PPh 2NHRh(cod)Cl}2], 2 and [C10H6N 2{NHPPh2Ir(eta5-C5Me 5)Cl2}2], 3, respectively. All new complexes have been fully characterized by analytical and spectroscopic methods. 1H31P-{1H} NMR, 1H13C HETCOR or 1H1H COSY correlation experiments were used to confirm the spectral assignments. 1, 2 and 3 are suitable catalyst precursors for the transfer hydrogenation of acetophenone derivatives. Notably [Ru((Ph 2PNH)2C10H6N2) (eta6-benzene)Cl2], 1 acts as an excellent catalyst, giving the corresponding alcohols in 98-99% yields in 10 min at 82 C (TOF ?600 h-1) for the transfer hydrogenation reaction in comparison to analogous rhodium or iridium complexes. This transfer hydrogenation is characterized by low reversibility under these conditions.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.SDS of cas: 37366-09-9. In my other articles, you can also check out more blogs about 37366-09-9
