Application In Synthesis of Ferrocenemethanol. Catalysts allow a reaction to proceed via a pathway that has a lower activation energy than the uncatalyzed reaction.

A series of 1H-1,2,3-triazole linked Ferrocenyl-methoxy-methyl-Isatin conjugates was synthesized and assayed for their anti-proliferative activities against estrogen-responsive as well as estrogen non-responsive cell lines. The non-cytotoxic conjugate 7l, with an optimum combination of octyl chain as spacer and methyl-substituent at the C-5 position of isatin, proved to be a promising hit with an IC50 value of 14.62 muM against MCF-7 and 79.63 muM against MDA-MB-231 cells, respectively. The observed anti-proliferative activities of active conjugates were further corroborated via docking studies carried out on estrogen receptor subtypes alpha and beta.

Neuronal activity and brain glucose metabolism are tightly coupled, where triggered neurotransmission leads to a higher demand for glucose. To better understand the regulation of neuronal activity and its relation to high-speed metabolism, development of analytical tools that can temporally resolve the transients of vesicular neurotransmitter release and fluctuations of metabolites such as glucose in the local vicinity of the activated neurons is needed. Here we present an amperometric biosensor design for rapid co-detection of glucose and the neurotransmitter dopamine. The sensor is based on the immobilization of an ultra-thin layer of glucose oxidase on to a gold-nanoparticle-covered carbon fiber microelectrode. Our electrode, by altering the potential applied at the sensor surface, allows for the high-speed recording of both glucose and dopamine. We demonstrate that, even though glucose is electrochemically detected indirectly through the enzymatic product and the electroactive dopamine is sensed directly, when exposing the sensor surface to a mixture of the two analytes, fluctuations in glucose and dopamine concentrations can be visualized with similar speed and at a millisecond time scale. Hence, by minimizing the enzyme coating thickness at the sensor surface, dual detection of glucose and dopamine can be realized at the same sensor surface and at time scales necessary for monitoring fast metabolic alterations during neurotransmission.

The potential utility of systematic synthetic strategy will be applicable to efficient generations of chemical libraries of compounds to find ‘hit’ molecules. Quality Control of Ferrocenemethanol

ProtoporphyrinIX-zinc oxide (PP-ZnO) nanohybrids have been synthesized for applications in photocatalytic devices. High-resolution transmission electron microscopy (HRTEM), X-ray diffraction (XRD), and steady-state infrared, absorption, and emission spectroscopies have been used to analyze the structural details and optical properties of these nanohybrids. Time-resolved fluorescence and transient absorption techniques have been applied to study the ultrafast dynamic events that are key to photocatalytic activities. The photocatalytic efficiency under visible-light irradiation in the presence of naturally abundant iron(III) and copper(II) ions has been found to be significantly retarded in the former case, but enhanced in the latter case. More importantly, femtosecond (fs) transient absorption data have clearly demonstrated that the residence of photoexcited electrons from the sensitizer PP in the centrally located iron moiety hinders ground-state bleach recovery of the sensitizer, affecting the overall photocatalytic rate of the nanohybrid. The presence of copper(II) ions, on the other hand, offers additional stability against photobleaching and eventually enhances the efficiency of photocatalysis. In addition, we have also explored the role of UV light in the efficiency of photocatalysis and have rationalized our observations from femtosecond- to picosecond-resolved studies.

Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms. In my other articles, you can also check out more blogs about 16009-13-5

Conducting crystals of alternating ferrocene and diiodoacetylene units assembled into supramolecular 1-D chains via I?pi(Cp) halogen bonds were prepared and structurally characterized. Their structure and conductivity were compared with the ferrocene cocrystals with phenyliodoacetylene (C6H5C2I) and 1,4-di(ethynyliodo)phenylene. Electrical conductivity measurements of the ferrocene-based cocrystals revealed comparatively high electron-hole type conductivity in the ferrocene (FcH)-diiodoacetylene (C2I2) pair, a 3-order decrease in combination with the 1,4-di(ethynyliodo)phenylene linker, and it is virtually extinguished with the monotopic 1,2-phenyliodoacetylene. The increased electric conductivity of compound 1 is rationalized in terms of a weak charge transfer through the I?piCp halogen bonds in the [Cp-Fe-Cp?I-CC-I?]n polymeric chains.

These cats are purrfectionists: The ChenPhos ligands (see structure) showed dramatically higher catalytic activity in the title reaction than their C 2-symmetric predecessor with two dimethylaminoethyl-substituted ferrocenyl(phenyl)phosphanyl groups. The ready accessibility, extreme air stability, and high enantioselectivity, activity, and productivity of these ligands make them very promising for a wide range of practical applications.

The two related compounds (R = OEt or ferrocenyl C5H4FeC5H5, Fc), have been prepared, the first by insertion of ethyl ethynyl ether (CH<*>COEt) into and the second by oxidative addition of ethenylferrocene (CH2 = CHFc) to respectively.Spectroscopically both compounds are similar to known related compounds with alkyl- or aryl-substituted vinyl ligands.A single-crystal X-ray structural study of each was made in an attempt to detect any structural effects of ?-donation by the substituents at the vinylgroup, such as was observed for .The latter compound has been shown to have a zwitterionic structure with an alkylidene bridge between two osmium atoms rather than the normal mu,eta2-vinyl mode of bonding.The two compounds studied here have essentially normal mu,eta2-vinyl bridges, but with some distortion towards the alkylidene bonding type, more pronounced for R = OEt.

The viability and activity of HeLa cells were probed using scanning electrochemical microscopy (SECM). The feedback generated by HeLa cells during scanning depends on the electrochemical mediator. Living HeLa cells generated positive feedback when ferrocene methanol (FcMeOH) was oxidized at the tip, showing that the cells reduced FcMeOH+. The positive feedback with FcMeOH changed to negative feedback when the HeLa cells were exposed to toxic treatments, i.e. CN- or UVC radiation, suggesting that FcMeOH+ reduction can be used to monitor cell activity. Living HeLa cells also accumulate FcMeOH after exposure times of a few h, but the presence of mM concentrations of FcMeOH has no apparent effect on the cell viability. The effect of Ag+ (known to be toxic to bacteria at the 10 muM level) on HeLa cells was probed using the FcMeOH as an indicator. The activity of the HeLa cells was not affected in a culture medium containing Ag+ up to 10 mM. The uptake of Ag+ by living and dead HeLa cells was small and nearly the same, indicating that even at high Ag+ concentrations in the culture medium, only a small amount of Ag+ is accumulated within the cells.

The iron 2p and carbon 1s near-edge X-ray absorption fine structure (NEXAFS) spectra of substituted ferrocene compounds (Fe(Cp-(CH3) 5)2, Fe(Cp)(Cp-COOH), Fe(Cp-COOH)2, and Fe(Cp-COCH3)2) are reported and are interpreted with the aid of extended Hiickel molecular orbital (EHMO) theory and density functional theory (DFT). Significant substituent effects are observed in both the Fe 2p and C 1s NEXAFS spectra. These effects can be related to the electron donating/withdrawing properties of the cyclopentadienyl ligands and their substituents as well as the presence of pi* conjugation between the cyclopentadienyl ligand and unsaturated substituents.
