In heterogeneous catalysis, catalysts provide a surface to which reactants bind in a process of adsorption. In homogeneous catalysis, catalysts are in the same phase as the reactants. Formula: C12H10FeO2. Catalysts allow a reaction to proceed via a pathway that has a lower activation energy than the uncatalyzed reaction. Introducing a new discovery about 1271-48-3, Name is 1,1′-Ferrocenedicarboxaldehyde
From the reaction of [PtCl2(N-CMe)2] with FcC-N (1) (Fc = Fe(eta5-C5H4)(eta5-C 5H5)) complex [PtCl2(FcC-N)(N-CMe)] (2) was obtained, which on subsequent treatment with 1 gave trans-[PtCl 2(N-CFc)2] (trans-3). The latter complex and the appropriate cis isomer (cis-3) were also accessible when [PtCl2] or [PtCl2(N-CMe)2] is reacted with a 2.6-fold excess of 1. Appropriate treatment of [PtCl2(N-CMe)2] with two equivalents of 1-acetyl-1′-cyanoferrocene (4) produced trans-[PtCl 2(Fe(eta5-C5H4CN)( eta5-C5H4C(O)Me))2] (trans-5). Coordination polymer [PtCl2(Fe(eta5-C5H 4CN)2)]n (7) was obtained by combining [PtCl2(N-CPh)2] with [Fe(eta5-C 5H4CN)2] (6). However, when 7 was reacted with PPh3 for deaggregation, [PtCl2(PPh3) 2] was formed. Addition of FcC-CLi (8-Li) to trans-3 gave pentametallic trans-[Pt(C-CFc)2(NH-CnBuFc)2] (10) via trans-[Pt(C-CFc)2(N-CFc)2] (9). When trans-3 is reacted with two equivalents of nBuLi in the absence of FcC-CH (8), trans-[PtCl2(NH-CnBuFc)2] (11) was obtained, which decomposed to FcC(-NH)nBu (12), giving FcC(O)nBu (13). Electrochemical measurements of the nitrile platinum complexes show no redox separation for the oxidation of the Fc and Fe(eta5-C 5H4)2 moieties. Compared with the noncoordinated ferrocenecarbonitriles, a shift to higher potentials is observed. In contrast, for 10 four well-separated redox events (-185, -90, +460, +545 mV) were found, which could be assigned to the oxidation of the Fc units. UV-vis/NIR spectroscopy allowed to determine an IVCT absorption (numax = 6495 cm-1, epsilonmax = 270 L·mol-1·cm-1, Deltanu1/2 = 2270 cm-1) for 10+, classifying this mixed-valent species as a weakly coupled class II system according to Robin and Day, while no IVCT transitions were observed for 10n+ (n = 2, 3). The structures of trans-3, cis-3, 10, and FcC(O)tBu (15) in the solid state were determined by single-crystal X-ray diffraction. Although the bond distances and angles of trans-3 and cis-3 are similar, the cis isomer crystallizes as a dimer possessing Pt-Pt distances within the sum of the van der Waals radii.
The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing theoretical assessments of solvent structures and their interactions with reaction intermediates and transition states. Formula: C12H10FeO2, you can also check out more blogs about1271-48-3
