Three ferrocene derivatives carrying different kinds of nitroxide radicals (1-3) were prepared as dual redox compounds. All of them have distorted molecular conformations between a Cp unit of a ferrocene group and a nitroxide group and the largest dihedral angle between the units is observed in the PO derivative 3. A unique magnetic behavior with a spin gap is disclosed in the derivative 3, reflecting two-dimensional interactions between the paired spins. Each derivative has two oxidation potentials based on both ferrocene and nitroxide groups and multi-step charge-discharge processes are found for all derivatives with the first discharge capacity over 200 A h kg-1.

Future efforts will undeniably focus on the diversification of the new catalytic transformations. We’ll also look at important developments of the role of 1273-86-5, and how the biochemistry of the body works.Reference of 1273-86-5

1,1?-Ferrocene biscarboxaldehyde (1) has been prepared and the aldehyde groups were subsequently protected with acetal groups to produce 1,1?-bisacetalferrocene (2). A ring-locked ferrocene was synthesised by further derivatisation of the cyclopentadiene rings at the 2,2? positions with phosphine substituents to produce 2,2?-bis-(acetal)-1,1?-diphenylphosphinoferrocene (3), which was subsequently coordinated to either a nickel chloride (5) or nickel bromide (6) metal centre. The ring-locked ferrocene complexes produced 2,5?-bis-(acetal)-1,1?-diphenylphosphinoferrocene substitution patterns. The acetal protecting groups of 2,2?-bis-(acetal)-1,1?-diphenylphosphinoferrocene were removed to produce 1,1?-bis-carboxaldehyde-2,2?-diphenylphosphinoferrocene (4). The Cp rings of 1,1?-bisacetalferrocene were also further derivatised at the 2,2? positions with a silane to produce the ring-locked 1,1?-siloxane-2,5?-bisacetalferrocenophane (7). The acetal protecting groups were removed from this to produce 1,1?-siloxane-2,5?-ferrocenophanecarboxaldehyde (8). For both the phosphine and siloxane electrophiles, the substitution on the Cp rings gives chiral products (obtained as racemic mixtures). Due to the highly regioselective nature of the reaction and diastereoselectivity in the products only C2-symmetric compounds were observed without the presence of meso diastereoisomers. Subsequent ring-locking forced the Cp rings to rotate, leading to 1,1?-ring-locked ferrocenes with 2,5?-arrangement of the acetal groups (i.e. on opposite faces of the ferrocene unit).

Ferrocenylmethy 1,2-dithiolane-3-pentanoate, which can be used to modify a gold electrode surface, was prepared by a condensation reaction with hydroxymethylferrocene and 1,2-dithiolane-3-pentanoic acid (D, L-alpha-lipoic acid). The condensation product has an 1,2-dithiolane ring which adheres to gold surfaces and a ferrocenyl group which is a redox site. The ferrocene rings on the modified electrode were electroactive in both acetonitrile and aqueous media.

Irreversible inhibitors are therefore the equivalent of poisons in heterogeneous catalysis.

Negative-feedback scanning electrochemical microscopy (SECM) is successfully applied to visualize spatially resolved differences in the topography of coated metal samples upon exposure to aqueous electrolyte solutions of different composition. This method allows the investigation of the uptake of reactants from the electrolyte phase through the polymeric matrix to the metal/polymer interface to be performed even at early exposures. Yet, the method must be carefully checked to discard transport processes from the organic matrix into the solution phase, such as those related to lixiviation. In this later case, the topography of the polymer layer may evolve with time accordingly, not longer exclusively responding to the uptake by the polymer matrix of components from the electrolyte phase. Furthermore, lixiviated species may also react with the SECM tip, eventually leading to the continuous modification of the active surface area of the electrode during the measurements. In this work, the effect of lixiviation from a nickel foil coated with plasticized PVC (PVC Plastisol) on its topographic characterization by SECM was investigated.

A stable palladium-decorated SBA-15 nanocomposite was simply fabricated through surface modification of SBA-15 with biguanide and subsequent metal/ligand coordination with Pd2+ from inexpensive commercially available starting materials and using standard laboratory techniques. The structure of this organic inorganic hybrid material was characterized by SEM, TEM, XRD, elemental analyzer, atomic absorption spectroscopy, N2 adsorption-desorption (BET), and FT-IR techniques. The catalytic performance of this novel heterogeneous catalyst was determined for the Suzuki cross-coupling and aerobic oxidation of benzyl alcohols. The composite exhibited an excellent catalytic activity and reuse ability of various recycles in air for the aforementioned organic transformations. TEM images of the recovered catalyst showed retained ordered mesostructure of SBA-15 with no damage in the periodic structure of the silicate framework and a good dispersion of in situ generated palladium nanoparticles within the SBA-15 structure.

The introduction of mechanophores into polymers makes it possible to transduce mechanical forces into chemical reactions that can be used to impart functions such as self-healing, catalytic activity, and mechanochromic response. Here, an example of mechanically induced metal ion release from a polymer is reported. Ferrocene (Fc) was incorporated as an iron ion releasing mechanophore into poly(methyl acrylate)s (PMAs) and polyurethanes (PUs). Sonication triggered the preferential cleavage of the polymers at the Fc units over other bonds, as shown by a kinetic study of the molar mass distribution of the cleaved Fc-containing and Fc-free reference polymers. The released and oxidized iron ions can be detected with KSCN to generate the red-colored [Fe(SCN)n(H2O)6?n)](3?n)+ complex or reacted with K4[Fe(CN)6] to afford Prussian blue.
