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. In a Article£¬once mentioned of 37366-09-9, name: Dichloro(benzene)ruthenium(II) dimer
16-electron (arene)ruthenium complexes with superbasic bis(imidazolin- 2imine) ligands and their use in catalytic transfer hydrogenation
The ligands N,N’-bis(l,3,4,5-tetramethylimidazolin-2-ylidene)-l,2- ethanediamine (BLMe) and N,N-bis(l,3-diisopropyl-4,5- dimethylimidazolin-2-ylidene)-l,2-ethanediamine (BLIPr) react with [(eta5-C5Me5)RuCl]4 to afford cationic 16electron half-sandwich complexes [(eta5-C 5Me5)Ru(BLR)]+ (R = Me, 3; R = iPr, 4), which resist coordination of the chloride counterion because of the strong electron-donating ability of the diimine ligands. Upon reaction with [(eta6-C6H6)RuCl2]2 or [(eta6-C10H14)RuCl2]2, these ligands stabilize dicationic 16electron benzene and cymene complexes of the type [(eta6C6H6)Ru(BLR)] 2+ (R = Me, 5; R = iPr, 6) and [(eta6-C 10H14)Ru(BLR)]2+ (R = Me, 7; R = iPr, 8). The X-ray crystal structure of [5]C12 reveals the absence of any direct Ru-Cl interaction, whereas a long Ru-Cl bond, supported by two CH-C1 hydrogen bonds, is observed for [(6)Cl]Cl in the solid state. Treatment of the dichlorides of 6 and 8 with NaBF4 affords [6](BF4) 2 and [8](BF4)2, which are composed of individual dications and tetrafluoroborate ions with no direct Ru-F interaction, All complexes catalyze the transfer hydrogenation of acetophenone in boiling 2-propanol Wiley-VCH Verlag GmbH & Co.

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.name: Dichloro(benzene)ruthenium(II) dimer, you can also check out more blogs about37366-09-9
