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, HPLC of Formula: C12H12Cl4Ru2
Reactions of pyrazole based ligand and halide bridged arene d6 metal precursors resulted a series of mono and di-substituted pyrazole based half sandwich d6 metal complexes. In general, they are formulated as [(arene)MLCl2] [M = Ru, arene = benzene (1), p-cymene (2), arene = Cp*, M = Rh (3) and Ir (4)] and [(arene)ML2Cl] [M = Ru, arene = benzene (5), p-cymene (6), arene = Cp*, M = Rh (7) and Ir (8)]. All these complexes were characterized by various spectroscopic techniques (IR, 1H NMR, ESI-MS, and UV/Vis). The molecular structures were confirmed by single-crystal X-ray diffraction technique. Spectroscopic studies revealed that complexation i.e., mono- and di-substitution occurred by the ratio-based reaction between pyrazole ligand and metal precursor through the neutral nitrogen rather than protic nitrogen. In these complexes deprotonation of the protic nitrogen does not occur unlike the other complexes containing pyrazole derivatives, in which the pyrazole ligand is anionic.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.HPLC of Formula: C12H12Cl4Ru2. In my other articles, you can also check out more blogs about 37366-09-9
