Related Products of 1293-65-8, Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In an article, 1293-65-8, molcular formula is C10Br2Fe, belongs to iron-catalyst compound, introducing its new discovery.

Starting from doubly lithiated ferrocene [Fe(eta5-C 5H4)2]3Li6(tmeda) 2 (1), the corresponding thf adduct [Fe(eta5-C 5H4)2]2Li4(thf) 6 (3) was prepared by recrystallization of 1 from thf. In contrast to 1, which features six Li+ cations surrounded by 1,1?- ferrocenediyl fragments in a carousel arrangement, compound 3 contains only two ferrocenediyl anions bridged by four Li+ cations. This comparison clearly reveals the strong impact of different supporting ligands on the solid-state structures of lithiated ferrocenes. The doubly magnesiated and zincated derivatives [Fe(eta-C5H4) (tmeda)2 (4) and [Fe(eta5-C5H4)2] 2Zn2(tmeda)2 (6) were synthesized via salt metathesis using 1 and MgCl2 or ZnCl2, respectively. Even though Mg2+ and Zn2+ are chemically related ions, the solid-state structures of 4 and 6 turned out to be distinctly different. Compound 4 possesses a cluster structure reminiscent of the lithiated aggregate 1, whereas 6 represents the first example of a first-row transition metal-bridged [1.1]-ferrocenophane (anri-conformation). All three doubly metallated ferrocenes 3, 4, and 6 are suitable reagents for the preparation of 1,1?-disubstituted ferrocenes as has been exemplified for the synthesis of Fe(eta5-C5H4SiMe3)2 (5). We have also shown that 5 can be generated in yields exceeding 90% from Fe(eta;5-C5H4Br)2, Me 3SiCl, and Rieke magnesium.

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: C12H3Fe. Catalysts allow a reaction to proceed via a pathway that has a lower activation energy than the uncatalyzed reaction. Introducing a new discovery about 1271-51-8, Name is Vinylferrocene

This paper describes the orbital configuration which provides a basis for the understanding of the electronic structure and spectroscopic properties of 17e and 18e FcC2R and FcC4R dyads, where R is H, 1-naphthyl, 9-anthryl, 3-pyrenyl, perylenyl. DFT calculations show that destabilisation of the ferrocenyl pi orbitals upon binding a C{triple bond, long}CR group to a Cp ring leads to the metal-based a1 orbital dropping below the e1-a so that the frontier orbital configuration is (e2? -a, pi)2 (e2? -b,metal)2 (e1? -a, pi)2, (a1, metal)2. The contribution of the aryl group to the pi e2-a and e1-a orbitals varies with the annelation of the ring. The LUMO is aryl based. The calculations are consistent with the spectroscopic data for the 18e species. Oxidation to the 17e cations does not change the orbital configuration but the orbital energies are lowered by the positive charge centred on the Fe. A strongly solvatochromic transition in the near-IR, a signature for the 17e cations, is best described as an LMCT transition but the contribution of C2R and C4R to the donor and acceptor levels depends on the ionization energy of the aryl pi orbital. LMCT energies decrease from FcC2R to FcC4R dyads.

Real time measurement of time-correlated ion transport and volumetric changes in electroactive materials is necessary to understand and model mechanoelectrochemistry. Reversible reduction and oxidation of soft electroactive materials such as conducting polymers result in the deformation of the material due to ion transport into and out of the polymer backbone. In cells, ion transport and volumetric expansion are collectively responsible for homeostasis that is essential for life functions and hence, mechanoelectrochemistry of cells is essential to understand cell and developmental biology. The characterization methods required to investigate mechanoelectrochemistry require nanoscale spatial resolution for the imaging of a redox active site in a polymer or a small group of transmembrane proteins in a single cell. Towards this goal, we present an imaging technique using scanning electrochemical microscopy (SECM) hardware with shear-force (SF) feedback for high bandwidth mechanoelectrochemistry characterization. In this proceedings article, we demonstrate this technique referred to as surface-tracked scanning electrochemical microscopy technique (ST-SECM) that is realized by measuring the structural feedback of the glass electrode to position the electrode in 10s of nanometers above the surface of a polypyrrole membrane doped with dodecylbenzenesulfonate (PPy(DBS)). Two ultra-microelectrodes of controlled dimensions (of 20 mum and 30 mum glass diameter) were fabricated using a hydrofluoric acid etching technique and were used to generate a spatially correlated ion storage map of PPy(DBS). We compare the developed technique to a three-dimensional discrete scan over the surface and show that a ST-SECM technique produces a higher resolution and takes approximately 200 fewer minutes as compared to the conventional technique.
