A Rural Perspective on Health Care for the Whole Person

The authors summarize the health care problems facing rural and frontier America by addressing five key issues within the framework of health care for the whole person: how to (a) provide health care access, (b) ensure health care quality, (c) provide a range of health care or meet the scope of practice demands, (d) address regional, rural-specific characteristics that may exist, and (e) address health professionals\u27 quality of life. When working in rural and frontier areas it is crucial for providers to collaborate across all types of health care to provide better care and better utilize a region\u27s tautly stretched resources. Rural health care resources are provided. The authors attempt to demonstrate characteristics of rural culture and rural and frontier populations\u27 health care disparities, highlighting the need for collaborative care.

Diastereoselective Formation Of An [Eta(4)-(1z)-Sulfinyl Diene]Iron(0) Tricarbonyl Complex. Diastereoselective Allylation Of The Derived Iron Dienal

An enantiomerically pure (1Z,3E)-sulfinyl diene exhibited a high degree of facial selectivity (alpha:beta = 16:1) upon complexation to an iron(0) tricarbonyl fragment, producing a [eta(4)-(1Z)-sulfinyl diene]iron(0) tricarbonyl complex (2; 80%). The iron(0)-dienal complex derived from 2 can undergo a highly diastereoselective allylation with allyltri-n-butylstannane and BF3 . Et(2)O (diastereomer ratio 95:5); the absolute stereochemistry of the homoallylic alcohol product (4) was established by X-ray crystallography

Synthetic, Structural, Photophysical and Computational Studies on π-Conjugated 1,3,2-Benzodiazaboroles with Carbazole Building Blocks

Weber L, Halama J, Werner V, et al. Synthetic, Structural, Photophysical and Computational Studies on π-Conjugated 1,3,2-Benzodiazaboroles with Carbazole Building Blocks. European Journal of Inorganic Chemistry. 2010;2010(34):5416-5425.The reaction of the N-lithiated 3,6-di-tert-butyl-carbazole (2) with 2-bromo-1,3-diethyl-1,3,2-benzodiazaborole (1a) and 2-bromo-1,3-diphenyl-1,3,2-benzodiazaborole (1b) afforded the 2-N-carbazolyl-functionalized benzodiazaboroles 3a and 3b as colourless solids in 77 and 73% yield, respectively. Synthesis of 2[5'-N-carbazolyl-2'-thienyl]-1,3-diethyl-1,3,2-benzodiazaborole (5a) was effected by lithiation of N-(2-thienyl)carbazole (4) and subsequent reaction with equimolar amounts of 1a, and 5a was obtained in 68% yield. Similarly, 2[5'-N-carbazolyl-2'-thienyl]-1,3-diphenyl-1,3,2-benzodiazaborole (5b) was prepared from lithiated 4 and 1b in 62% yield. Compounds 3a,b and 5a,b are characterized by elemental analyses, IR and NMR spectroscopy (H-1, B-11, C-13) and mass spectrometry. The molecular structures of 3a and 5a were elucidated by X-ray diffraction analysis. These borylated systems show intense blue luminescence. The spectroscopic results were reproduced by TD-DFT calculations at the [B3LYP/6-311G (d,p)] level of theory

The synthesis and one- and two-photon optical properties of dipolar, quadrupolar and octupolar donor-acceptor molecules containing dimesitylboryl groups

C. Katan present address: CNRS UMR6082 FOTON, INSA de Rennes, 20 avenue des Buttes de Coësmes, CS 70839, 35708 RENNES cedex 7, FranceInternational audienceTwo series of related donor-acceptor conjugated dipolar, pseudo-quadrupolar (V-shaped) and octupolar molecular systems based on the p-dimesitylborylphenylethynylaniline, namely 4-(4-dimesitylborylphenylethynyl)-N,N-dimethylaniline, 4-[4-(4-dimesitylboryl-phenylethynyl)phenylethynyl]-N,N-dimethylaniline, 4,4'-bis(4-dimesitylborylphenyl-ethynyl)-N-n-butylcarbazole and tris[4-(4-dimesitylborylphenylethynyl)phenyl]amine, and on the E-p-dimesitylborylethenylaniline motif, namely E-4-dimesitylborylethenyl-N,N-di(4-tolyl)aniline, 4,4'-bis(E-dimesitylborylethenyl)-N-n-butylcarbazole and tris(E-4-dimesitylborylethenylphenyl)amine have been synthesized, by palladium catalyzed cross-coupling and hydroboration routes respectively. Their absorption and emission maxima, fluorescence lifetimes and quantum yields have been obtained and their two-photon absorption spectra and two-photon absorption (TPA) cross-sections have been examined. Of these systems, the octupolar compound tris-(E-4-dimesitylborylethenylphenyl)amine has been shown to exhibit by far the largest two-photon absorption cross-section among the two series and amount to about 1000 GM at 740 nm. Its TPA performance is comparable to those of other triphenylamine based octupoles of similar size
