The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.32993-05-8, Name is Chlorocyclopentadienylbis(triphenylphosphine)ruthenium(II), molecular formula is C41H35ClP2Ru.

Synthesis of a ruthenium(II) complex containing an [11]ane-P 2CNHC (NHC = Imidazolidin-2-ylidene) macrocycle
Reaction of [RuCl(Cp)(PPh3)2] with bis[di(2-fluorophenyl)phosphino]benzene, 3, yields complex [RuCl(Cp)(3)], [4]. The chloro ligand in [4] can be exchanged for the 2-azidoethyl isocyanide ligand 2, giving complex [Ru(Cp)(2)(3)]Cl, [5]Cl, which reacts with NH 4BF4 to give [5]BF4. The azido group of the coordinated isocyanide ligand in [5]C1 or [5]BF4 can be reduced with Zn/NH4Cl/H2O to give the complex with the 2-aminoethyl isocyanide ligand. This ligand is not stable but cyclizes by an intramolecular nucleophilic attack of the amino group at the isocyanide carbon atomto give an NH, NH-stabilized NHC ligand in complexes [6]X (X = Cl, [6]C1; X = 0.5 ZnCl 4, [6]2(ZnCl4); X = BF4, [6]BF 4). Deprotonation of the NH,NH-stabilized NHC ligands in cations of type [6]+ leads to an intramolecular nucleophilic attack of the amido nitrogen atoms at the fluorinated phenyl groups of the diphosphine ligand under formation of the complex with the facially coordinated macrocyclic [11]ane-P2CNHC ligand [1]X (X = Cl, [1]Cl; X = 0.5 ZnCl4, [1]2(ZnCl4); X = BF4, [1]BF4). Formation of the macrocycle is facilitated by the steric pressure excerted by the cyclopentadienyl ligand. The molecular structures of [4], [5]BF4, [6]BF4-CH2Cl2, and [1]Cl¡¤CH2Cl2¡¤0.5H2O have been determined by X-ray diffraction.
The reactant in an enzyme-catalyzed reaction is called a substrate. Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction.I hope my blog about 32993-05-8 is helpful to your research., name: Chlorocyclopentadienylbis(triphenylphosphine)ruthenium(II)
