Heterometallic platinum(ii) compounds with beta-aminoethylferrocenes: Synthesis, electrochemical behaviour and anticancer activity

A new family of heterometallic compounds 3-6 containing ferrocenyl and platinum(ii) centers has been synthesized by reaction of 1-beta- aminoethylferrocene (1) and 1,1?-bis(beta-aminoethyl)ferrocene (2) with Pt(ii) precursors. Using K2[PtCl4] as the Pt(ii) source, the cis-square-planar neutral compounds [Fe{eta5-C 5H4(CH2)2NH2} 2PtCl2] (3) and [{Fe(eta5-C5H 4(CH2)2NH2)(eta5-C 5H5)}2PtCl2] (5) were obtained. Reaction of cis-[PtCl2(dmso)2] with 1 and 2 resulted in the displacement of dmso and chloride ligands from the platinum coordination sphere, affording the cationic and neutral compounds [Fe{eta5- C5H4(CH2)2NH2} 2Pt(dmso)Cl]Cl (4) and [Fe(eta5-C5H 4(CH2)2NH2)(eta5-C 5H5)Pt(dmso)Cl2] (6). Compounds 3-6 were thoroughly characterized using multinuclear (1H, 13C, 195Pt) NMR, IR spectroscopy, ESI mass spectrometry and elemental analysis. Single-crystal X-ray analysis of heterometallic 6 confirmed the cis geometry of the molecule and revealed that the platinum atom is held in a perfect square-planar geometry. The electrochemical behaviour of the heterometallic compounds 3-6, which has been examined by cyclic (CV) and square wave (SWV) voltammetries in dichloromethane and dmso solution, is characterized by the reversible one-electron oxidation of the ferrocene moieties. The results of the biological activity studies revealed that the organometallic complex 5 is active against all cell lines with GI50 values in the range 1.7-2.3 muM. When compared to the standard anticancer drug cisplatin, heterotrimetallic 5, possessing two aminoethylferrocenyl units coordinated to the Pt(ii) center, showed a greater activity profile in the colon cancer cell line. Cell cycle studies revealed that the new mixed compound exhibits a mechanism of action different to cisplatin.

Studies on the cyclomercuration of 1,1?-bis[(arylimino)phenylmethyl]ferrocenes

The reaction of bisferrocenylimines with mercuric acetate and subsequent treatment with LiCl lead to formation of mono (9) and double (10) cyclomercurated derivatives. The 1H NMR and 199Hg NMR spectra of the double cyclomercurated bisferrocenylimines show that compounds 10 exist as two isomers (meso and dl). The individual stereoisomers were isolated successfully by crystal picking. The structures of these new compounds have been confirmed by elemental analysis, IR and 1H NMR spectroscopies, and further by X-ray crystal structure determination of meso [{HgCl(eta5-C5H3CPh=NAr)}2Fe] (Ar=m-CH3C6H4).

Characterization of coating systems by scanning electrochemical microscopy: Surface topology and blistering

Operation of the scanning electrochemical microscope used in feedback mode over a coated metal allows changes in the state of the coating surface to be monitored during immersion in aqueous electrolytes. This paper reports changes in the coating induced by specific anions in the electrolyte in situ during immersion. Significant surface roughening is observed for immersion times shorter than 1 day when the electrolyte contains chloride ions. This effect is also observed when the oxygen dissolved in the electrolytic phase is employed as redox mediator for SECM imaging. The coated system exposed to chloride-free electrolytes containing sulphate or nitrate maintains a featureless topography within the same time scale. The observed features are due to the nucleation and growth of blisters at the metal/coating interface induced by chloride ions in the environment. The implication is that ionic migration occurs simultaneously with the absorption of water by the coating already from the beginning of exposure to the aqueous environment. The unique role of chloride ions compared with sulphate or nitrate ions towards coating performance has been established at a very early stage following immersion of the sample.

The effects of drying time and relative humidity on the stability of sol-gel derived silicate films in solution

The stability of thin silicate films in solution has been evaluated as a function of drying time and drying conditions using scanning probe microscopy and an electrochemical probe technique. In these experiments, the silicate films were spin coated on various substrates using a sol formed by the acid catalyzed hydrolysis and condensation of tetramethoxysilane. The silicate films were then dried under a relative humidity of 25, 50, or 75% for 3, 12, 24, or 48 h. After drying, the films were immediately placed in a solution of potassium nitrate or a solution of a redox probe, specifically ferrocene methanol, ruthenium hexaammine, or cobalt phenanthroline. Cyclic voltammetry in conjunction with atomic force microscopy was used to monitor the disruption in gel structure as the films sat in aqueous solution. The stability of each film was found to be essentially independent of the substrate it was coated on but a strong function of the length of the drying time and the relative humidity under which it was dried. Films that were dried at 25% humidity for 48 h stayed on the electrode for several days. In contrast, films that were dried at 75% humidity for 3 h fell off the electrode within 24 h.

Cyanoferrocenes as redox-active metalloligands for coordination-driven self-assembly

Ferrocene-based Lewis bases have found utility as metalloligands in a wide variety of applications. The coordination chemistry of cyanoferrocenes however, is underexplored. Herein, we describe a new synthetic protocol for the generation of cyanoferrocenes. The coordination chemistry of these metalloligands to [Cu(NCMe)4][PF6], [(PPh3)2Cu(NCMe)2][PF6] and [(dppf)Cu(NCMe)2][PF6] salts has been explored, providing crystallographic evidence of cluster and polymeric forms of 1,1?- and 1,2-dicyanoferrocene complexes. The stability of the complexes and ligand dissociation were found to be strongly solvent-dependent.

Acyl-substituted ferrocenes as driers for solvent-borne alkyd paints

Ferrocenes bearing acyl substituents in the cyclopentadienyl rings [Fe(eta5-C5H4COR)(eta5-C 5H5)] and [Fe(eta5-C5H 4COR)2] (R = CH3, CF3 and Ph) were examined as new driers for solvent-borne alkyd binder. All studied ferrocenes were found to be active catalysts for cross-linking reaction of the alkyd. These iron(II) compounds give solid polymeric films with hardness and drying time comparable to the commercial cobalt(II) drier. Acetyl- and benzoyl-substituted ferrocenes show an excellent synergic effect with the cobalt drier giving hard polymeric films within short drying time. The kinetics of the alkyd autoxidation was followed by FTIR spectroscopy. Spin-trapping ESR technique has proven the important role of the ferrocenium cation upon decomposition of hydroperoxides by ferrocene-based driers. The peroxy and alkoxy radicals, appearing in drying process, were resolved by the new spin trap methyl-N-mesityl nitrone.

Photolysis of diacylferrocenes and their photo-ligand exchange reactions with 1,10-phenanthroline

The photolysis of 1,1?-diacylferrocenes Fc(COR)2 (Fc = Ferrocenyl, R = CH3,Ph) in the presence of 1,10-phenanthroline (phen) in deoxygenated acetonitrile under irradiation with visible light has been studied. In these photolysis systems the phen has two important roles to play: one is to stabilize the photo-liberated Fe2+ by coordination, and the other is to promote the photolysis through photo-ligand exchange. Under this condition the photoproducts were isolated in definite composition and characterized by single crystal X-ray diffraction, 1H NMR spectroscopy, IR spectroscopy, photolysis-cyclic voltammetry and elemental analysis. The mechanism of the reactions was demonstrated to be charge transfer from metal to acylcyclopentadienyl ring, leading to cleavage of the bond between them. The phen attacks the Fe2+ ion to give the stable tris (1,10-phenanthroline) iron(II) complex cation and the acylcyclopentadienyl ring detaches from the Fe2+ ion, giving the enolate anion in the outer sphere of the complex.
