Meso-substituted corroles bearing directly linked ferrocene unit have been synthesized for the first time. Among various methods studied, only the condensation of pentafluorophenyldipyrromethane with a formylferrocene led to this type of product. A triad containing corrole and porphyrin bridged with ferrocene has been obtained by a convergent approach. Bilanes were used as crucial substrates in the porphyrin-forming step. For the first time it was shown that H2O-MeOH-HCl conditions are suitable for preparation of various 10-(formylaryl)corroles via the direct condensation of aromatic dialdehydes with dipyrromethanes. Electrochemical studies of 10-ferrocenyl-5,15-bis(pentafluorophenyl)corrole support the possibility of intramolecular electron transfer from the corrole to the ferrocene system after the electrode oxidation of the ferrocene to a ferrocenium cation. We have studied the structure of 1-(corrolyl)-1?-(porphyrinyl)ferrocene by 1H NMR and UV-Vis. NMR spectra show that this compound has more conformational freedom than analogous, previously studied bis- porphyrinylferrocenes. Absorption spectra suggest the lack of strong electronic interaction between ferrocene and porphyrinoids for dyads and significant conjugation for the triad.

Introducing a new discovery about 1273-86-5, Name is Ferrocenemethanol

Electrochemical studies of the free ferrocenylphosphine ligands FcCH2PR2 (Fc=(eta5-C5 H5)Fe(eta5-C5H4); R=Ph, CH2OH and CH2CH2CN) and some phosphine oxide, phosphine sulfide, phosphonium and metal derivatives are described. The free ligands exhibit complex voltammetric responses due to participation of the phosphorus lone pair in the redox reactions. Uncomplicated ferrocene-based redox chemistry is observed for PV derivatives and when the ligands are coordinated in complexes cis-PtCl2[FcCH2P(CH2OH) 2], PdCl2[FcCH2P(CH2OH) 2], [Au{FcCH2P(CH2OH)2} 2]Cl, RuCl2(eta6-C10 H14)[FcCH2P(CH2OH)2] and RuCl2(eta6-C10H14) (FcCH2PPh2). The reaction pathways of the free ligands after one-electron oxidation have been examined in detail using voltammetry, NMR spectroscopy and electrospray mass spectrometry. Direct evidence for formation of a P-P bonded product is presented.

Herein is described the synthesis of (+)-camphor derivatives containing sulfonamide groups, ferrocenylmethylidene or arylidene moieties. The obtained derivatives were tested against seven human cancer cells lines, namely BV-173, K-256a, NB-4, A549, H1299, MCF-7, and MDA-MB231, and two normal human cell lines, HEK293 and HUVEC, in order to determine their activity against malignant cells. Some of them exhibit IC50 values below 10 muM in at least one of the cancer cell lines. Ferrocenylmethylidene ketone 16 can be outlined as the most potent and selective in the current study (IC50 for cancer cells-up to 4.0 muM; IC50 for HEK293 and HUVEC-68 and 69 muM, respectively). There is a clear trend showing that the presence of a conjugated ferrocenylmethylidene group is essential for the cytotoxicity, however different sulfonamide substituents and derivatization of the carbonyl group can modify the activity. Thus, this class of compounds could have good prospects for further structural optimisation.

The d4 halide complexes [MX(CO)(eta-RCCR)Tp?] {X = F, Cl, Br or I; R = Me or Ph; M = Mo or W; Tp? = hydrotris(3,5- dimethylpyrazolyl)borate} undergo one-electron oxidation to the d3 monocations [MX(CO)(eta-RCCR)Tp?]+, isolable for M = W, R = Me. X-Ray structural studies on the redox pairs [WX(CO)(eta-MeCCMe)Tp?] z (X = Cl and Br, z = 0 and 1), the ESR spectra of the cations [WX(CO)(eta-RCCR)Tp?]+ (X = F, Cl, Br or I; R = Me or Ph), and DFT calculations on [WX(CO)(eta-MeCCMe)Tp?]z (X = F, Cl, Br and I; z = 0 and 1) are consistent with electron removal from a HOMO (of the d4 complexes) which is pi-antibonding with respect to the W-X bond, pi-bonding with respect to the W-C(O) bond, and delta-bonding with respect to the W-Calkyne bonds. The dependence of both oxidation potential and nu(CO) for [MX(CO)(eta-RCCR)Tp?] shows an inverse halide order which is consistent with an ionic component to the M-X bond; the small size of fluorine and its closeness to the metal centre leads to the highest energy HOMO and the lowest oxidation potential. In the cations [MX(CO)(eta-RCCR)Tp?] + electronegativity effects become more important, leading to a conventional order for Cl, Br and I. However, high M-F pi-donation is still facilitated by the short M-F distance. The Royal Society of Chemistry.

Alkylation reactions of [Pt2(mu-S)2(PPh 3)4] with haloalkylferrocenes FcCH2Cl, Fc(CH2)6Br and Fc(CH2)11Br [Fc = (eta5-C5H5)Fe(eta5-C5H4)] gave the cationic mu-thiolate complexes [Pt2(mu-S){mu-S(CH2) nFc}(PPh3)4]+ (n = 1, 6, 11), isolated as PF6 and/or BPh4 salts, and characterised by ESI mass spectrometry, NMR spectroscopy, microelemental analysis, and by an X-ray structure determination on [Pt2(mu-S){mu-SCH2Fc} (PPh 3)4]PF6. The complex contains the typical folded {Pt2(mu-S)2} core with an axial ferrocenylmethylthi-olate ligand. The corresponding selenolate complex [Pt 2(mu-Se){mu-SeCH2Fc}(PPh3) 4]+ was similarly obtained by alkylation of [Pt 2(mu-Se)2(PPh3)4] with FcCH 2Cl, and isolated as PF6 and BPh4 salts. The attempted liberation of FcCH2SH from [Pt2(mu-S){mu- SCH2Fc}(PPh3)4]+ using Na 2S was not successful.

In a patent，Which mentioned a new discovery about 1271-48-3

Grinding of 1,1?-ferrocenedicarboxaldehyde with a 2.2 molar equivalent of an aromatic amine in a solvent-free environment provided excellent yields of 1,1?-ferrocenyldiimines. After mixing the aldehyde and amines, a gum or melt formed which eventually solidified to the product. An analytically pure sample of the product was obtained by cold recrystallization. Grinding of ferrocenecarboxaldehyde and 4-substituted phenylacetonitriles under solvent-free conditions provided good yields of the corresponding ferrocenylacrylonitriles. The yield in this reaction was very low when the substituent group para to the acetonitrile group was electron-donating.

Career opportunities within science and technology are seeing unprecedented growth across the world, Quality Control of Vinylferrocene, and those who study chemistry or another natural science at university now have increasingly better career prospects. In a patent，Which mentioned a new discovery about 1271-51-8

In this article, we report the noncovalent linkage of terminal substituted oligo(dimethylsiloxanes) bearing cyclodextrins (CD) as host endgroups and adamantan or ferrocene, respectively, as guest endgroups. Structural characterization was performed by 1H NMR-, IR-, and mass spectroscopy. Electron microscopy studies show significant differences in the surface structure of the individual derivatives. In addition, the ferrocene-terminated di-and poly(dimethylsiloxanes) are distinguished by a red-ox activity and reversibility, which also makes the complexes between the ferrocene- and CD functionalized siloxanes switchable via electrochemical stimuli. The evidence for a successful complexation of the end groups, and thus the successful supramolecular formation of the siloxane strands, was even performed by shift of the protons in the 1H NMR spectra.

The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing theoretical assessments of solvent structures and their interactions with reaction intermediates and transition states.

Recommanded Product: 1273-86-5, Academic researchers, R&D teams, teachers, students, policy makers and the media all rely on us to share knowledge that is reliable, accurate and cutting-edge. In a document type is Article, and a compound is mentioned, 1273-86-5, name is Ferrocenemethanol, introducing its new discovery.

The electrochemical kinetics for the oxidation of ferrocenemethanol (FcCH2OH) over the whole composition range of dimethyl sulfoxide (DMSO)-water solutions of different viscosities (I·) containing 50.0 mM (CH3)4NClO4 (TMAP) at a Pt microelectrode was studied using scanning electrochemical microscopy (SECM). The measured diffusion coefficient, DFcCH2OH, as well as the standard rate constant of the heterogeneous electron transfer, k0, as a function of solution composition, showed a minimum at about a DMSO molar fraction (xDMSO) of 0.33, corresponding to the mixture with the maximum solution viscosity. The largest k0 value found, 2.06 A± 0.31 cm s-1 in pure water (electrolyte) medium, was about 15 times larger than that obtained in the solution of xDMSO = 0.33 (0.14 A± 0.02 cm s-1). A good linear correlation between ln k0 and ln I· was observed within the solution composition range of 0.10 a¿¿ xDMSO a¿¿ 0.60. An excellent linear correlation between ln k0 and ln I¿L, the longitudinal relaxation time, was also obtained with a slope equal to 1.0 when xDMSO = 0-0.60. Unusually small rate constants found in the solutions of xDMSO a¿¥ 0.70 were attributed to adsorption effects at the tip and the substrate electrode. The k0 obtained for the present system was generally found to be inversely proportional to the viscosity of the solution and directly proportional to the diffusion coefficient of the electroactive species.

In a document type is Article, and a compound is mentioned, 1273-86-5, name is Ferrocenemethanol, introducing its new discovery.

Ferrocenylmethanol acrylate (FcMA)-immobilized polystyrene latex particles were synthesized by copolymerizing FcMA and styrene in the presence of polystyrene latex suspensions with eight different diameters ranging from 0.084 to 1.7 mum. The amounts of the ferrocenyl moiety loaded on one particle were proportional to the radii, a. The proportionality suggests the uniform distribution of the ferrocenyl moiety over the particle, of which concentration was 0.18 M. The aqueous suspensions, which were stable in the presence of a surfactant, exhibited reversible voltammetric waves for the ferrocenyl moiety. The peak current was controlled by diffusion of the latex particles. The efficiency of the reaction was obtained from the ratio of the observed current to the theoretical one which was estimated from the number of the ferrocenyl moieties and the diffusion coefficient of the particle by the Stokes-Einstein relation. The ratio was proportional to a-0.47, whereas it might be a0 for an ideal particle without any size effect. This relation was explained in terms of the contribution of rotational diffusion of redox particles.

The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing theoretical assessments of solvent structures and their interactions with reaction intermediates and transition states.
