Substituent influence on charge transfer interactions in alpha,alpha?-Diferrocenylthiophenes

Within a series of alpha,alpha?-diferrocenylthiophenes, the influence of electron-withdrawing substituents at the ferrocenyl moieties and electron-donating functionalities at the thiophene bridge on the electronic behavior was studied. The synthesis of the appropriate 2,5-fc2-cC4H2S and 2,5-fc2-3,4-(OCH2CH2O)-cC4S compounds (fc = Fe(eta5-C5H4)(eta5-C5H4R); R = H (1, 5), 3,5-(CF3)2-cC6H3 (2, 6), CHO (3, 7), C?N (4, 8)) was carried out using the Negishi C,C cross-coupling protocol to effect the coupling of the thiophene and the ferrocenyl moieties. The corresponding diferrocenylthiophenes were characterized spectroscopically. Within this context, the structural properties of 2-5, [5][B(C6F5)4], 6, and 8 in the solid state were investigated by single-crystal X-ray diffraction studies. Electrochemical investigations of thiophenes 2-8 demonstrated an increasing redox separation and hence thermodynamic stability of the corresponding mixed-valent species in the series 1 < 3 < 5 < 4 ? 2 < 6 < 7 < 8. Moreover, UV/vis/near-IR and infrared spectroelectrochemical studies verify these observations. These studies further reveal a valence trapped situation in corresponding mixed-valent species and allow a class II classification according to Robin and Day. (Figure Presented) Substituent influence on charge transfer interactions in alpha,alpha?-Diferrocenylthiophenes The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis. We will look forword to the important role of 1293-65-8, and how the biochemistry of the body works.Related Products of 1293-65-8

Synthesis and hydrolysis of [alkenyl(alkoxy)carbene]manganese complexes: Evidence for a transient allylic intermediate on the way to alpha,beta-unsaturated aldehydes

A variety of alkenylcarbene complexes [Cp'(CO)2Mn= C(OEt)CH=CHR] (3) (Cp’ = TiS-MeCsH4) was obtained in a straightforward manner upon aldol condensation of [Cp'(CO)2Mn=C(OEt)CH3] (1) with aromatic and alpha,beta- unsaturated aldehydes RC(H)O (2). The reaction is totally stereoselective, giving (E)- or (all-E)-alkenylcarbenes only. The protonation of 3 at low temperature followed by reaction with water affords the alpha,beta-unsaturated aldehyde complexes [Cp'(CO)2Mn(n2-RCH=CHCHO] (5), from which the aldehydes RC(H)=C(H)C(H)O (6) were displaced by acetonitrile. The intermediate aldehyde complexes are shown to result from the hydrolysis of a transient cationic pi- allyl species [Cp'(CO)2Mn(n3-RCHCHC(OEt)H]+ ([4]+) formed upon protonation of 3.

Nanoscale polypyrrole sensors for near-field electrochemical measurements

Scanning electrochemical microscopy (SECM) is an electrochemical technique that is used to measure redox activity local to the surface of a sample. The incorporation of shear force (SF) feedback into SECM enables the concurrent acquisition of topographical data. Contemporary SECM measurements require a redox mediator (such as ferrocene methanol (FcMeOH)) for electrochemical measurements; however, redox mediators are detrimental to chemically sensitive materials such as biological cells. In this article, nanoscale polypyrrole membranes doped with dodecylbenzene sulfonate (PPy(DBS)) are deposited at the tip of highly sensitive ultra-microelectrodes (UME) to demonstrate a novel modification of the contemporary SECM?SF imaging technique that operates in the absence of a redox mediator. This technique leverages the redox activity of a PPy(DBS) membrane to locally detect changes in cation concentration. In conjunction with SF imaging, the PPy(DBS) membrane can (i) detect changes in distance from the surface by measuring changes in ion concentration of the diffusion shell, or (ii) detect local cation flux due to cell function when kept at a constant distance from the cell surface through SF-imaging techniques. Therefore, we predict this technique to enable high resolution mapping of surface cation concentrations and impact the field of biological imaging.

Direct electron-transfer anisotropy of a site-specifically immobilized cellobiose dehydrogenase

To study the direct electron transfer (DET) of the multicofactor enzyme cellobiose dehydrogenase (CDH) in regard to its orientation on an electrode surface, a recently published, maleimide-based immobilization method was used in combination with site-directed mutagenesis to establish different orientations on an electrode surface. CDH from Myriococcum thermophilum was chosen for this study because its protein structure is resolved and the factors influencing the movement of its mobile cytochrome domain (CYT) are established. Seven CDH variants with a surface-exposed cysteine residue in different spatial positions were generated for site-specific maleimide coupling. Surface plasmon resonance and cyclic voltammetry showed that all CDH variants, but not the wild-type CDH, bound covalently to gold electrodes or glassy carbon electrodes and were catalytically active. For DET, the CYT domain needs to move from the closed-state conformation, where it obtains an electron from the catalytic flavin adenine dinucleotide (FAD) cofactor to the open state where it can donate an electron to the electrode. We therefore hypothesized that the mobility of the CYT domain and its distance to the electrode is central for DET. We found that the uniform spatial orientations of CDH influenced DET as follows: An orientation of the two-domain enzyme on the side, with CYT in proximity to the electrode, resulted in high DET currents. Orientations with a bigger distance between CYT and the electrode, or orientations where CYT could not swing back to the dehydrogenase domain to form the closed enzyme conformation, reduced DET. In the latter case, calcium ions that stabilize the closed conformation of CDH fully recovered DET. The study demonstrates that a mobile CYT domain can compensate unfavorable orientations of the catalytic domain to a great extent and allows CDH as a multicofactor enzyme to transfer electrons even in awkward orientations. The mobile CYT domain reduces the anisotropy of DET, which is also essential for CDH’s physiological function as an extracellular, electron-transferring enzyme.

C-N Bond Formation Catalyzed by Ruthenium Nanoparticles Supported on N-Doped Carbon via Acceptorless Dehydrogenation to Secondary Amines, Imines, Benzimidazoles and Quinoxalines

Ruthenium nanoparticles (NPs) supported on N-doped carbon (Ru/N?C) were prepared by the pyrolysis of cis-Ru(phen)2Cl2 loaded onto carbon powder (VULCAN XC72R) at 800 C. Ru/N?C NPs (0.2 mol% Ru) selectively catalyzed either acceptorless dehydrogenation coupling (ADC) or auto-transfer-hydrogen (ATH) reactions of amines with alcohols to imines and secondary amines. Such selectivity could be controlled by the choice of alkali metal ion associated with the base. Under similar catalytic conditions, the ADC cross-coupling of diamines with primary alcohols or diols afforded the corresponding benzimidazoles and quinoxalines in good to excellent yields. This catalytic system displayed good activity, recyclability, and wide applicability to a diverse range of substrates.
