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. 13991-08-7, Name is 1,2-Bis(diphenylphosphino)benzene, molecular formula is C30H24P2.

Study of the effect of the phosphane bridging chain nature on the structural and photophysical properties of a series of gold(I) ethynylpyridine complexes
Alkynyl AuI complexes of the type [Au(C?CC 5H4N)(PPh3)] (1) [Au2(C? CC5H4N)2 (diphosphane)] [diphosphane = bis(diphenylphosphanyl)methane (2), bis(diphenylphosphanyl)isopropane] (3), bis(diphenylphosphanyl)acetylene (4), 1,2-bis(diphenylphosphanyl)ethane (5), 1,3-bis(diphenylphosphanyl)propane (6), 1,4-bis(diphenylphosphanyl)butane (7), 1,1?-bis(diphenylphosphanyl)ferrocene (8) and [Au3(C? CC5H4N)3(triphos)] [triphos = 1,1,1-tris(diphenylphosphanylmethyl)ethane] (9) were prepared by reaction of [Au(C?CC5H4N)]n with the suitable phosphane. Determination of the X-ray crystal structures of several compounds bearing different carbon backbones between the phosphorus atoms reveals the influence of the nature of the phosphane spacer on the establishment of intra and/or intermolecular gold-gold interactions. The absorption and emission properties of the complexes were analysed by taking into account the presence or absence of intermetallic interactions. Although UV/Vis spectra show differences for compounds with intramolecular Au-Au contacts, a conclusive trend was not observed in the emission behaviour. Wiley-VCH Verlag GmbH & Co. KGaA, 2008.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.Recommanded Product: 1,2-Bis(diphenylphosphino)benzene, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 13991-08-7, in my other articles.
