COMPLEXATION OF alpha-FERROCENYLMETHYLCARBENIUM TETRAFLUOBORATES BY ETHERS; AN NMR STUDY

The tetrafluoborates of the primary, secondary, and tertiary ferrocenylmethyl carbenium ions have been prepared from the corresponding carbinols in ethyl ether, tetrahydrofuran and t-butyl methyl ether by adding HBF4.The NMR spectra of these salts, which dissolve in CDCl3, are characterized by the presence of very strong signals attributed to the ether used in the preparation, the solubility depending upon the structure of the cation and that of the ether.The NMR data suggest that alpha-ferrocenylcarbenium ions undergo two distinct types of solvation with ether-like donor molecules; one involves a much stronger interaction than the other.

Molecular and solid state structure of the doubly-substituted ?-diketone 3,3′-bis(ferrocenylmethyl)pentane-2,4-dione

ABSTRACT The ferrocene-containing ?-diketone, 3-ferrocenylmethyl-pentane-2, 4-dione 1, has been synthesized by reacting ferrocenyl methanol with acetylacetone in the presence of cerium(IV) ammonium nitrate as catalyst in C-C bond formation, and isolated as an orange oily product in 90% yield. The doubly-substituted 1,3-diketone, 3,3′-bis(ferrocenylmethyl)pentane-2,4-dione 2 was isolated as orange crystals in 79% yield, upon standing a dichloromethane solution of 1 at -30 C for two weeks. Both complexes have been authenticated by spectroscopic methods, mass spectrometry, and cyclic voltammetry. In addition, the molecular identity and geometry of 2 has been confirmed by single-crystal X-ray diffraction analysis. In the crystal lattice, the molecules pack as dimers through C-HO hydrogen bondings, where weaker C-Hp interactions link the dimeric units to form a chain structure.

Graphene Microelectrode Arrays for Electrical and Optical Measurements of Human Stem Cell-Derived Cardiomyocytes

Introduction: Cell?cell communication plays a pivotal role in biological systems? coordination and function. Electrical properties have been linked to specification and differentiation of stem cells into targeted progeny, such as neurons and cardiomyocytes. Currently, there is a critical need in developing new ways to complement fluorescent indicators, such as Ca2+-sensitive dyes, for direct electrophysiological measurements of cells and tissue. Here, we report a unique transparent and biocompatible graphene-based electrical platform that enables electrical and optical investigation of human embryonic stem cell-derived cardiomyocytes? (hESC-CMs) intracellular processes and intercellular communication. Methods: Graphene, a honeycomb sp2 hybridized two-dimensional carbon lattice, was synthesized using low pressure chemical vapor deposition system, and was tested for biocompatibility. Au and graphene microelectrode arrays (MEAs) were fabricated using well-established microfabrication methods. Au and graphene MEAs were interfaced with hESC-CMs to perform both optical and electrical recordings. Results: Optical imaging and Raman spectroscopy confirmed the presence of monolayer graphene. Viability assay showed biocompatibility of graphene. Electrochemical characterization proved graphene?s functional activity. Nitric acid treatment further enhanced the electrochemical properties of graphene. Graphene electrodes? transparency enabled both optical and electrical recordings from hESC-CMs. Graphene MEA detected changes in beating frequency and field potential duration upon beta-adrenergic receptor agonist treatment. Conclusion: The transparent graphene platform enables the investigation of both intracellular and intercellular communication processes and will create new avenues for bidirectional communication (sensing and stimulation) with electrically active tissues and will set the ground for investigations reported diseases such as Alzheimer, Parkinson?s disease and arrhythmias.

alpha-Amino Aldehydes as Readily Available Chiral Aldehydes for Rh-Catalyzed Alkyne Hydroacylation

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.

Elucidating connectivity and metal-binding structures of unlabeled paramagnetic complexes by13C and1H solid-state NMR under fast magic angle spinning

Characterizing paramagnetic complexes in solids is an essential step toward understanding their molecular functions. However, methodologies to characterize chemical and electronic structures of paramagnetic systems at the molecular level have been notably limited, particularly for noncrystalline solids. We present an approach to obtain connectivities of chemical groups and metal-binding structures for unlabeled paramagnetic complexes by 13C and 1H high-resolution solid-state NMR (SSNMR) using very fast magic angle spinning (VFMAS, spinning speed ?20 kHz). It is experimentally shown for unlabeled Cu(II)(Ala-Thr) that 2D 13CV1H correlation SSNMR under VFMAS provides the connectivity of chemical groups and assignments for the characterization of unlabeled paramagnetic systems in solids. We demonstrate that on the basis of the assignments provided by the VFMAS approach multiple13C-metal distances can be simultaneously elucidated by a combination of measurements of 13C anisotropic hyperfine shifts and 13C T1 relaxation due to hyperfine interactions for this peptide-Cu(II) complex. It is also shown that an analysis of 1H anisotropic hyperfine shifts allows for the determination of electron-spin states in Fe(III)-chloroprotoporphyin-IX in solid states.
