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. 32993-05-8, Name is Chlorocyclopentadienylbis(triphenylphosphine)ruthenium(II), molecular formula is C41H35ClP2Ru. In a Article，once mentioned of 32993-05-8, Computed Properties of C41H35ClP2Ru
The new tert-butylnitroso complexes W(CO)5(N(O)But) (1), [CpFe(CO)(PPh3)(N(O)But)]+ (2), [CpRu(PPh3)2(N(O)But)]+ (3), and CpMn(CO)2(N(O)But) (4) have been prepared and spectroscopically characterized. Complexes 1 and 2 have been further defined by crystallographic studies. The nitroso ligands of both complexes are coordinated via the nitrogen atom, and in each case the nitroso ligand is oriented in such a way as to maximize its pi bonding to the metal. EHMO calculations on the model complex (W(CO)5(N(O)Me) show that the nitroso molecule acts as a sigma-donor, pi-acceptor ligand with the LUMO being an antibonding combination of a metal dxz orbital and a NO pi orbital. The LUMO is calculated to lie only approximately 0.7 eV above the filled, largely nonbonding dxy, dyz orbitals, giving rise to a low-energy metal-to-ligand charge-transfer transition in the visible spectral region, which accounts for the intense color of these ButN=O complexes.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.Computed Properties of C41H35ClP2Ru, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 32993-05-8, in my other articles.
