Visible Light Promoted 2-Bromotetrafluoroethylation of Nitrones

A reaction of nitrones with 1,2-dibromotetrafluoroethane affording bromodifluoroethyl-substituted hydroxylamines is described. The process is performed in the presence of a ruthenium photocatalyst and ascorbic acid as a stoichiometric reducing agent and is mediated by blue light irradiation. The fluroalkylation products can undergo chemoselective transformations involving either N?O or C?Br bonds furnishing various tetrafluorinated compounds. (Figure presented.).

High loading of graphene oxide/multi-walled carbon nanotubes into PDLLA: A route towards the design of osteoconductive, bactericidal and non-immunogenic 3D porous scaffolds

We have prepared a novel 3D porous biomaterial combining poly (dl-lactic acid) (PDLLA) and graphene and multi-walled carbon nanotubes oxides (MWCNTO-GO) composite. PDLLA as control and a high loading of PDLLA/MWCNTO-GO (50/50 w/w) bioscaffolds were prepared and functionalized. MWCNTs were exfoliated to form MWCNTO-GO by oxygen plasma etching. The later was also applied to enhance the scaffolds wettability, attaching oxygen-containing groups on their surfaces. This approach produced a porous architecture observed by scanning electron microscopy and semi-quantified by electrochemical analysis. The later also indicated a notable increase on the conductivity of PDLLA/MWCNTO-GO scaffold compared to MWCNTO-GO free PDLLA (about 5 orders of magnitudes at low frequencies). Thermogravimetric analysis showed that the MWCNTO-GO acted protecting the PDLLA matrix, enhancing its thermal stability. The PDLLA/MWCNTO-GO scaffolds had significant cellular adhesion, did not present cytotoxicity effect, besides reduced bactericidal proliferation and produced mineralized tissues in SBF media. The metallic MWCNTO-GO powder held together by PDLLA polymer opens a whole new branch of applications, including bioelectroanalyses, drug delivery systems and tissue engineering.

An Enantioselective Oxidative C-H/C-H Cross-Coupling Reaction: Highly Efficient Method to Prepare Planar Chiral Ferrocenes

A Pd-catalyzed, asymmetric oxidative cross-coupling reaction between ferrocenes and heteroarenes is described. The process, which takes place via a twofold C-H bond activation pathway, proceeds with modest to high efficiencies (36-86%) and high levels of regio- and enantioselectivity (95-99% ee). In the reaction, air oxygen serves as a green oxidant and excess amounts of the coupling partners are not required. The process is the first example of a catalytic asymmetric biaryl coupling reaction that occurs via double C-H bond activation. Finally, the generated coupling products can be readily transformed into chiral ligands and catalysts.

Lab on a tip: Applications of functional atomic force microscopy for the study of electrical properties in biology

Electrical properties, such as charge propagation, dielectrics, surface potentials, conductivity, and piezoelectricity, play crucial roles in biomolecules, biomembranes, cells, tissues, and other biological samples. However, characterizing these electrical properties in delicate biosamples is challenging. Atomic Force Microscopy (AFM), the so called ?Lab on a Tip? is a powerful and multifunctional approach to quantitatively study the electrical properties of biological samples at the nanometer level. Herein, the principles, theories, and achievements of various modes of AFM in this area have been reviewed and summarized. Statement of Significance: Electrical properties such as dielectric and piezoelectric forces, charge propagation behaviors play important structural and functional roles in biosystems from the single molecule level, to cells and tissues. Atomic force microscopy (AFM) has emerged as an ideal toolkit to study electrical property of biology. Herein, the basic principles of AFM are described. We then discuss the multiple modes of AFM to study the electrical properties of biological samples, including Electrostatic Force Microscopy (EFM), Kelvin Probe Force Microscopy (KPFM), Conductive Atomic Force Microscopy (CAFM), Piezoresponse Force Microscopy (PFM) and Scanning ElectroChemical Microscopy (SECM). Finally, the outlook, prospects, and challenges of the various AFM modes when studying the electrical behaviour of the samples are discussed.

Inter-versus intraannular ring-closing metathesis of polyallylferrocenes: Five-fold RCM within a single molecule

Treatment of decaallylferrocene (1) with the Grubbs-II catalyst in refluxing dichloromethane has promoted the 5-fold ring-closing metathesis in 1 to afford single-bridged bis(1,4,5,8-tetrahydrofluorenyl)iron(II) species 3 in excellent yield. The preferential formation of 3 over quintuply bridged “superferrocenophane” 2 was explained as the intraannular RCM process being preferred over the interannular one in the reactions of polyallylferrocenes.

NMR Studies of Low-Spin Ferric Complexes of Natural Porphyrin Derivatives. 4. Proton Relaxation Characterization of the Dimer Structure of Dicyanohemin in Aqueous Solution

Concentration dependent chemical shifts, line widths, and spin-lattice relaxation rates of dicyanohemin at pH 9 can be attributed to intermolecular paramagnetic dipolar relaxation processes within a stereospecific dimer.The r-6 dependence of the relaxation rates permits determination of the dimer structure which consists of overlap of presumably parallel porphyrin planes (ca. 5-Angstroem separation) with the 2-vinyl and 3-methyl groups of each porhyrine in contact with the aromatic ?-system of the other porphyrin and the propionate side sections extending into the solvent.This structure points to the important role of hydrophobic interactions in stabilizing the dimer.At higher pH values, particularly at higher temperatures (> 25 deg C), the dicyanohemin undergoes displacement of cyanide by one or more hydroxide ions.

Synthesis, crystal structures and electrochemical properties of ferrocenyl imidazole derivatives

Six ferrocenyl imidazole derivatives substituted with -Cl, -NO2 and -CH3 on the 2-position of the 1H-imidazole ring have been synthesized. Of the six compounds, the di-substituted ferrocenes, i.e. compounds 4 (1,1?-ferrocenylmethyl(2-chloroimidazole)), 5 (1,1?-ferrocenyl(2-nitroimidazole)), and 6 (1,1?-ferrocenylmethyl(2-methylimidazole)) are reported for the first time. The structure-property relationships of compounds 4, 5 and 6 were investigated by means of UV-visible, FTIR, 1H-NMR, 13C-NMR spectroscopy and electrochemical studies. UV-visible analysis in acetonitrile showed that the pi -pi* band of compounds 2 (1-ferrocenylmethyl(2-nitroimidazole)) and 5 appeared at longer wavelength compared to 1 (1-ferrocenylmethyl(2-chloroimidazole)), 3 (1-ferrocenylmethyl(2-methylimidazole)), 4 and 6. This phenomenon is due to the different electronics around the imidazole moieties. In cyclic voltammetry analysis, all compounds exhibited a quasi-reversible redox wave for the ferrocenyl and imidazole moieties. Density functional theoretical (DFT) calculations with the B3LYP/6-311+G(d) basis set were performed on compounds 1?6, and the calculated HUMO-LUMO band gap energies correlated with those obtained from electrochemical and spectroscopic data. The X-ray crystallographic analysis highlighted the effect of electron-withdrawing and electron-donating substituents on the conformation of the cyclopentadienyl rings attached to the ferrocenyl moiety.

Synthesis and biological activity of ferrocenyl derivatives of the non-steroidal antiandrogens flutamide and bicalutamide

A series of ferrocenyl derivatives of the two non steroidal antiandrogens flutamide and bicalutamide have been prepared. Ferrocenyl bicalutamide complexes were initially synthesized in their racemic forms, and subsequently prepared as pure (R) and (S) enantiomers, and their structure was determined by X-ray crystallography. Most of the complexes retain a modest affinity for the androgen receptor and show an antiproliferative effect on both hormone-dependent (LNCaP) and -independent (PC-3) prostate cancer cells. Ferrocenyl derivatives of bicalutamide are the most cytotoxic (IC50 values on PC-3 around 15 muM); however, they are less potent than the ferrocenyl derivatives of ethynyltestosterone or nilutamide (IC50 around 5 muM).
