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, Recommanded Product: 1,1-Bis(diphenylphosphino)ferrocene
Reaction of Cp4Fe4(CO)4 (1) with RLi and HBF4 in sequence affords Cp3Fe4(CO)4(C5H4R) (R= Me, Bun, and Ph) in moderate yields. Further sequential PhLi/HBF4 treatment of Cp3Fe4(CO)4(C5H4Ph) produces Cp2Fe4(CO)4(C5H4Ph) 2. On the other hand, 1 reacts with lithium diisopropylamide (LDA) and bromoferrocene sequentially to produce a ferrocenylated cluster [Cp3Fe4(CO)4(C5H 4)][(C5H4)FeCp] (3) and a double cluster [Cp3Fe4(CO)4(C5H4)] 2 (2). A similar LDA/dibromoferrocene treatment with 1 leads to 2, [Cp3Fe4(CO)4(C5H 4)][(C5H4)(C5H4Br)Fe] (4), and a ferrocenyl-bridged double cluster [Cp3Fe4(CO)4(C5H4)] 2[(C5H4)2Fe] (5). The new compounds have been characterized by elemental analysis and IR, mass, and NMR spectroscopy.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.Recommanded Product: 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.
