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. 37366-09-9, Name is Dichloro(benzene)ruthenium(II) dimer, molecular formula is C12H12Cl4Ru2. In a Article，once mentioned of 37366-09-9, Application In Synthesis of Dichloro(benzene)ruthenium(II) dimer
The bis(oxazoline) ligand, 2,2-bis[4(R)-phenyl-1,3-oxazolon-2-yl]propane (bpop), was introduced to the eta6-benzeneruthenium(II) moiety on treatment with [Ru(eta6-C6H6)Cl2]2 to give [Ru(eta6-C6H6) (bpop)Cl]+. Aquo and amine complexes [Ru(eta6-C6H6) (bpop) (L)]2+ (L=H2O (1), NH2R; R=H (2), Me (3), and n-Bu (4)) were prepared by treating the chloride complex with AgBF4 in the presence of L. X-ray structure determinations of 1 and 3 were carried out. Both complexes possessed a three-leg piano stool structure with the N or O donors located at the three corners of a pseudo octahedron. The aquo complex 1 exhibited a dynamic NMR feature in which two magnetically non-equivalent oxazoline parts observed at lower temperatures were interchanged with each other at higher temperatures. This observation was ascribed to the formation of a C2-symmetric 16-electron intermediate via Ru-OH2 cleavage, which is slower in acetone than in dichloromethane owing to more effective solvation by acetone around hydrogens of the coordinated water molecule. The two diastereotopic N-hydrogens of 4 underwent deuterium exchange with CD3OD with greatly different rates from each other owing to different energy of NH…O(D)(CD3) interaction. Carboxylate and sulfonate ions (A-) formed second sphere complexes with 4 by means of NH…A- hydrogen bonding, as evidenced by continuous shift of NH2 resonances with increasing amounts of the anions added.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.Application In Synthesis of Dichloro(benzene)ruthenium(II) dimer, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 37366-09-9, in my other articles.
