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, Safety of Dichloro(benzene)ruthenium(II) dimer
Reaction of <(eta6-C6H6)RuCl2>2 with pyrazole (Hpz) in appropriate molar ratio at room temperature in H2O/CH3OH yields the products <(eta6-C6H6)Ru(mu-Cl)(mu-pz)2Ru(eta6-C6H6)>Cl (1a) and <(eta6-C6H6)Ru(mu-Cl)2(mu-pz)Ru(eta6-C6H6)>Cl (2a), the structure of which were established by an X-ray study.Analogous binuclear complexes 3a and 4a were prepared with 4-methylpyrazole (4MepzH).The facile Cl-/OH- exchange in these complexes has been studied by 1H NMR spectroscopy to elevated temperatures.The hydroxo-bridged complexes <(eta6-C6H6)Ru(mu-OH)(mu-pz)2Ru(eta6-C6H6)>Cl (1b) and <(eta6-C6H6)Ru(mu-OH)2(mu-pz)Ru(eta6-C6H6)>Cl (2c) were also be prepared directly from <(eta6-C6H6)RuCl2>2 and pyrazole by refluxing in H2O/CH3OH solution.Reaction of <(eta6C6H6)RuCl2>2 with 6-azauracil (6auraH)Ru(eta6-C6H6)>Cl (6), the crystal structure of which is reported.A chloro-bridged binuclear complex could not be prepared; the analogous reaction in methanol alone gives <(eta6-C6H6)RuCl2(6auraH2)> (7).
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.Safety 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.
