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. 15746-57-3, Name is Cis-Dichlorobis(2,2′-bipyridine)ruthenium(II), molecular formula is C20H16Cl2N4Ru.

Electron-transfer chemistry of Ru-linker-(heme)-modified myoglobin: Rapid intraprotein reduction of a photogenerated porphyrin cation radical
We report the synthesis and characterization of RuC7, a complex in which a heme is covalently attached to a [Ru(bpy)3]2+ complex through a -(CH2)7- linker. Insertion of RuC7 into horse heart apomyoglobin gives RuC7Mb, a Ru(heme)-protein conjugate in which [Ru(bpy)3]2+ emission is highly quenched. The rate of photoinduced electron transfer (ET) from the resting (Ru2+/Fe 3+) to the transient (Ru3+/Fe2+) state of RuC7Mb is > 108 s-1; the back ET rate (to regenerate Ru2+/Fe3+) is 1.4 ¡Á 107 s-1. Irreversible oxidative quenching by [Co(NH3)5Cl] 2+ generates Ru3+/ Fe3+: the Ru3+ complex then oxidizes the porphyrin to a cation radical (P.+); in a subsequent step, P.+ oxidizes both Fe3+ (to give Fe IV=O) and an amino acid residue. The rate of intramolecular reduction of P.+ is 9.8 ¡Á 103 s-1; the rate of ferryl formation is 2.9 ¡Á 103 s-1. Strong EPR signals attributable to tyrosine and tryptophan radicals were recorded after RuC7MbM3+ (M = Fe, Mn) was flash-quenched/frozen.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.SDS of cas: 15746-57-3, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 15746-57-3, in my other articles.
