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. In a Article，once mentioned of 15746-57-3, Formula: C20H16Cl2N4Ru
Synthetic amino acids suitable for the assembly of small, redox-active metallopeptides are described. Nalpha-((1,1-Dimethylethoxy)carbonyl)-N ?-(2-pyridylmethyl)-L-lysine (1), Nalpha-acetyl-S-(2-pyridylmethyl)-L-cysteme (2), and Nalpha-acetyl-S-(2-(2-pyridyl)ethyl)-L-cysteine (3) have been synthesized by alkylation of the Nalpha-protected amino acids. Their [Ru(bipy)2]2+ complexes [(bipy)2Ru(BocLysCH2py)]2+ (4), [(bipy)2Ru(AcCysCH2py)]2+ (5), and [(bipy)2Ru-(AcCys(CH2)2py)]2+ (6) have been prepared by reactions of the ligands with [Ru(bipy)2Cl2]. On the basis of 1H-NMR spectroscopy, 4-6 can be described best as trans-tetrapyridine complexes with the lysine amino N atom and the cysteine S atom occupying one of the apical positions. It was shown by luminescence spectroscopy that 4 can serve as a possible photoredox-active module for the construction of photochemically active peptides. The redox properties of the complexes are described with the aid of the Lever parameters. It was demonstrated that the amino acid ligands in 5 and 6 can be viewed as methionine units. Particularly interesting is the unique redox chemistry of 4. Upon metal oxidation, a two-electron ligand oxidation occurred, followed by fast hydrolytic cleavage of the lysine-methylpyridine N-C bond. The physical and chemical properties of the compounds are discussed in terms of future applications in biomimetic chemistry such as the activation of small molecules.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Formula: C20H16Cl2N4Ru. In my other articles, you can also check out more blogs about 15746-57-3
