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. 12150-46-8, Name is 1,1-Bis(diphenylphosphino)ferrocene, molecular formula is C34H28FeP2. In a Article，once mentioned of 12150-46-8, Application In Synthesis of 1,1-Bis(diphenylphosphino)ferrocene
Reactions of [Pt3(mu-CO)3(PCy3)3] (1) and [Pt3(mu-CNXyl)2(mu-CO)(CNXyl)(PCy3) 2] (2) (Cy = C6H11, Xyl = C8H9) with 1/2 equiv of a bifunctional metal phosphine cation [(MPR?2)2(R)]2+ (M = Cu, Ag, Au; R = C6H4, (CH2)2C6H4, Fe(C5H5); R? = C6H5, C6H11) yielded quantitatively [{Pt3(mu-CO)3(PCy3)3} 2{(MPR?2)2 (R)}]2+ and [(Pt3(mu-CNXyl)2-(mu-CO)(CNXyl)(PCy3) 2}2{(MPR?2)2(R)}] 2+, respectively. The compounds were characterized by IR-, MS-, and 31P-NMR spectroscopy. The X-ray structure is given for [{Pt3(mu-CO)3(PCy3)3} 2{(AuPPh2)2(CH2)2C 6H4)}][PF6]2 (14), which crystallizes in the triclinic space group P1 with Z= 1, a = 15.350 A. b = 17.150 A, c = 20.446 A, alpha = 84.54, beta= 84.84, and gamma = 64.56. The structure was refined to R = 0.0435 for the 8430 observed reflections (I > 3sigma(I)).
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.Application In Synthesis of 1,1-Bis(diphenylphosphino)ferrocene, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 12150-46-8, in my other articles.
