The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.37366-09-9, Name is Dichloro(benzene)ruthenium(II) dimer, molecular formula is C12H12Cl4Ru2.

Transfer hydrogenation of ketones and catalytic oxidation of alcohols with half-sandwich complexes of ruthenium(II) designed using benzene and tridentate (S, N, E) type ligands (E = S, Se, Te)
The complexes of composition fac-[(eta6-C6H 6)Ru(L)][PF6][X] (1-6; X = PF6 or Cl), formed by reacting 2-MeSC6H4CH=NCH2CH 2E-C6H4-4-R (L1-L3) and 2-MeSC 6H4CH2-NHCH2CH2E-C 6H4-4-R (L4-L6) (where E = S or Se, R = H; E = Te, R = OMe) with [{(eta6-C6H6)RuCl(mu-Cl)} 2] and NH4PF6, have been characterized by 1H, 13C{1H}, 77Se{1H}, and 125Te{1H} NMR spectroscopy and X-ray crystallography. The Ru-Se and Ru-Te bond lengths are in the ranges 2.4837(14)-2.4848(14) and 2.6234(6)-2.6333(7) A, respectively. Complexes 1-6 have been found to be efficient catalysts for catalytic oxidation of alcohols with N-methylmorpholine-N-oxide, tBuOOH, NaOCl, and NaIO4 and transfer hydrogenation reaction of ketones with 2-propanol. The TON values are up to 9.9 ¡Á 104 and 9.8 ¡Á 104 for two catalytic processes, respectively. The oxidation probably involves the formation of intermediate species having Ru(IV)=O. Complexes 1-3 are as efficient as 4-6 for transfer hydrogenation of ketones. In transfer hydrogenation, the mechanism does not appear to be dependent on the availability of hydrogen on nitrogen and probably involves Ru-H bond formation. The catalytic efficiency for both processes follows the order Te > Se > S, which may be due to the presence of a MeO group on Te.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Application In Synthesis of Dichloro(benzene)ruthenium(II) dimer, you can also check out more blogs about37366-09-9
