The catalytic hydrogenolysis of 1,2-disubstituted ferrocenes having planar chirality and functional groups such as carboxyl (including ester) or tertiary amino proceeds under mild conditions (1 atm of H2, Pd/C, CF3COOH, 50 deg C) with the retention of functional groups in the cyclopentane products.Stereosectivity has been observed for the examples investigated, the diastereomeric ratio, trans: cis being close to 4:1, but optically inactive products are formed the enantiomeric ferrocenes.In contrast, hydrogenolysis of enantiomeric alpha-(N,N-dimethylamino)ethylferrocene gives an optically active alpha-(N,N-dimethylamino)ethylcyclopentane with retention of configuration at the alpha-carbon, whose bonds are not affected during the hydrogenolysis.

In order to investigate the ways in which heterogeneous kinetics at semiconductor electrodes are affected by various combinations of the formal reduction potentials of solution species and the energetic condition of the electrode surface. The authors have measured cyclic voltammetric dark currents in acetonitrile solutions for cobaltocene and a number of ferrocene derivatives at highly doped p-InP electrodes. Proper interpretation of the cyclic voltammetric data requires specific knowledge of the energetics at the semiconductor electrode/solution interface. This information has been derived from capacitance data that was obtained in the same solutions and within the same potential regions as the cyclic voltammetry and with experiments.

This work proposes the use of an electronic tongue based on flow injection coulometry for the rapid determination of the antioxidant capacity of fresh lettuce. The e-tongue consisted of a series of 16 porous carbon electrodes, each poised at a fixed potential from +100 to +850 mV. Each injection leaded to a characteristic hydrodynamic voltammogram, whose profile reflects the composition of antioxidants. The correlation between the peak area recorded by each sensor and the 1,1-Diphenyl-2-picryl-hydrazyl (DPPH) assay was maximum in the range of potentials between +400 and 750 mV (R2>0.97). Accordingly, the charge measured provided a direct and simple index of the antioxidant capacity. The practical utility of such index was initially demonstrated by determining the best extraction conditions. This consisted in freeze-drying of lettuce followed by methanolic extraction. Later, the e-tongue was used to evaluate the effect of storage (one week at 5 C) on lettuce. The e-tongue revealed that lettuce lost up to 25 % of their initial antioxidant activity during storage. However, when lettuce samples were pre-treated with fast cooling or vacuum cooling, the decrease of the antioxidant index was limited to 14 and 15 %. Overall, the e-tongue is a rapid, simple and sensitive method for the determination of the antioxidant capacity of fresh lettuce samples. Indirectly, these findings suggest also that lettuce may serve as potential dietary sources of natural phenolic antioxidants.

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 1273-86-5

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.

Readily available alpha-amino aldehydes, incorporating a methylthiomethyl (MTM) protecting group on nitrogen, are shown to be efficient substrates in Rh-catalyzed alkyne hydroacylation reactions. The reactions are performed under mild conditions, employing a small-bite-angle bis-phosphine ligand, allowing for good functional group tolerance with high stereospecificity. Amino aldehydes derived from glycine, alanine, valine, leucine, phenylalanine, isoleucine, serine, tryptophan, methionine, and cysteine were successfully employed, as was an enantiomerically enriched alpha-OMTM-aldehyde derived from phenyllactic acid. The synthetic utility of the alpha-amino enone products is demonstrated in a short enantioselective synthesis of the natural product sphingosine.

An ultrasensitive sandwich-type electrochemical biosensor for microRNA (miRNA) detection is developed based on magnesium oxide (MgO) nanoflower and graphene oxide?gold nanoparticles (GO?AuNPs) hybrids coupling with electrochemical?chemical?chemical (ECC) detection system. In this bioassay system, MgO nanoflowers and AuNPs are modified on electrode to act as sensing platform. The thiolated capture probe is then self-assembled onto AuNPs/MgO substrate via formation of Au-S bonds. Subsequently, a biotinylated DNA signal probe is conjugated to GO?AuNPs hybrids. When miRNA-21 is added, a sandwich complex is formed and a lot of signal indicators streptavidin-conjugated alkaline phosphatases (SA-ALP) are immobilized upon electrode by the specific reaction between avidin and biotin. Finally, ECC reaction is performed in the system to improve detection signal. The proposed sandwich-type assay benefits from advantages of sandwich-type structure for enhanced sensitivity and specificity, MgO nanoflowers/AuNPs as sensing platform and GO?AuNPs hybrids as signal carriers for signal amplification, and ECC as a sensitive detection system for low detection limit. This biosensor exhibits a good dynamic ranging from 0.1 to 100 fM and a low detection limit of 50 aM (S/N = 3) toward target miRNA-21.
