Ylide Complexes of Alkali and Earth Alkaline Metals, VI. Neutral and Anionic Ferrocenylmethylides and Fluorenylides

Coordination properties of phosphorus ylides towards electropositive metals are greatly improved in systems, where the carbanionic charge can be delocalized into the aromatic rings of substituents, as illustrated in the title compounds.The ferrocenyl-substituted ylide 2, synthesized from bis(diphenylphosphino)methane and (ferrocenyl)trimethylammonium iodide via the phosphonium salt intermediate 1, is thus easily converted into the alkali complexes 3a, b on treatment with NaNH2 or KH in tetrahydrofuran, respectively.The intensely coloured products are soluble in a number of organic solvents.NMR spectra of these solutions provide evidence for an interaction between alkali cations and the ferrocenyl rings. – From (C6H5)2CH2P(C6H5)2 and ferrocenylmethyl chloride a diquaternary salt 4 is obtained, which yields a double-ylide mixture 5a, b on treatment with base.Hydrolysis of this product affords the ylidic phosphine oxide 6. – The reaction of the ylides 7 and 9 (described previously) with NaNH2, KH or barium metal (in liquid ammonia) leads to the (earth) alkali complexes 8a-c and 10a, b, respectively.With the exception of 8c, but similar to 3a, these materials contain tetrahydrofuran solvate molecules.The 23Na NMR spectrum of 8a and the pronounced quadrupole broadening of the P(III) signals by the alkali cations in the 31P NMR spectra of 8a, b allow structural suggestions for the solution state as proposed in the formulae.Further treatment of 10b with KH yields a potassium complex 11, characterized, i.a., via a corresponding diquaternary salt 12. – Keywords: Ylides, Alkali Complexes, Phosphonium Salts, Phosphonium Ferrocenylmethylides

Cation participation during the redox switching of poly(vinylferrocene) films in aqueous 0.05 M perchlorate solutions: Part 1: Cyclic voltammetry and the EQCM

Mobile species transfer accompanying the redox switching of poly(vinylferrocene) (PVF) in aqueous perchlorate solutions of four cations was investigated using the electrochemical quartz crystal microbalance (EQCM). Cyclic voltammetry in 0.05 M solutions containing hydronium, sodium, rubidium or tetraethylammonium cation was employed. The mass transients could not be explained solely in terms of anion and solvent transport processes. EQCM transient data showed that the cation as well as perchlorate and water transport participated in the redox switching process in the four bathing solutions. Results and interpretation of the experimental approach are presented.

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).

Synthesis of versatile intermediates of the ferrocene series: Reductive amination of ferrocenecarbaldehyde

Reductive amination of ferrocenecarbaldehyde with several primary and secondary amines in the presence of sodium triacetoxyborohydride was studied. This method was used for the synthesis of new ferrocenylmethylamines, viz., N-(ferrocenylmethyl)isoleucine methyl ester, N,N-bis(ferrocenylmethyl)glycine ethyl ester, and N-(3,5-dibenzyloxybenzyl)-N-(ferrocenylmethyl)methylamine. The latter is a potential precursor of a dendrimer with the chiral ferrocenyl plane in the core.

Electron transfer in mixed-valence polyferrocenium cations: Preparation, electrochemistry, and 57Fe Moessbauer characteristics

Convenient new methods are developed for the preparation of 1?,1??-disubstituted triferrocenes and tetraferrocenes that can be oxidized with iodine to a new series of mixed-valence compounds. The X-ray structures of 1?,1??-diethyltriferrocene, 1?,1??-dimethoxymethyltriferrocene, and 1?,1??-dimethoxymethyltetraferrocene have been determined at 298 K. The rates of intramolecular electron transfer in these mixed-valence cations were estimated by variable-temperature 57Fe Moessbauer experiments. The features in all 80 and 300 K spectra include two doublets, one with a quadrupole splitting (DeltaEQ) of ?2 mm s-1 (Fe(II) site) and the other with DeltaEQ = ?0.3 mm s-1 (Fe(III) site). This pattern of two doublets is expected for a mixed-valence biferrocenium cation that is valence-trapped on the time scale of the Moessbauer technique (electron-transfer rate Recommanded Product: 1,1′-Dibromoferrocene, which selectively inhibits one of the enzymes involved in the synthesis of molecules that trigger inflammation. you can also check out more blogs about 1293-65-8

Hemin in vitro interaction with the anticancer drug doxorubicin: Absorption and emission monitoring

The doxorubicin – hemin interaction was studied by absorption and emission spectroscopy. The absorption spectra outline two processes, in function of the concentration range of hemin. The fluorescence emission of doxorubicin shows a pronounced hypochromic effect in presence of hemin. The best fit was obtained using an (1:1) and (1:2) interaction for both methods. The doxorubicin – hematoporphyrin and doxorubicin – FeIII systems were also investigated in similar experimental conditions, in order to outline the possible binding sites involved in the interaction. The quenching effect of hematoporphyrin is smaller than that of hemin, the binding parameters indicated an (1:1) interaction and are smaller than the corresponding values for hemin. For the doxorubicin – FeIII system, the association constants for (1:1) and (1:2) complexes are in a reasonable agreement in both methods used. Our results are consistent with a two site binding model, where the Fe III ions of hemin are involved to a higher extent than the planar porphyrin moiety in the hemin – doxorubicin interaction.
