Asymmetric Nitrene Transfer Reactions with Azides via Co(II)-Based Metalloradical Catalysis (MRC)Tao, Jingran 01 January 2013 (has links)
Asymmetric nitrene transfer reactions via metalloradical catalysis (MRC) with
azides has attracted research interest because of its fundamental and practical importance.
The resulting nitrogen-containing units are recurrent motifs in biologically important
molecules and can serve as versatile precursors in organic synthesis.
The [Co(D2-Por*)] have emerged as a new class of catalysts for asymmetric
aziridination and C-H amination. These metalloradical catalysts have been shown to be
highly effective for the asymmetric intermolecular aziridination of a broad scope of
substrates with different classes of azides with excellent to good enantioselectivity. The
intramolecular C-H amination utilizing various azides can allow for the construction of
diverse nitrogen containing heterocyclic compounds.

Raman spectroscopy of Co2+ in MgO and of b- In2Se2Trudel, Jacques, 1948- January 1983 (has links)
We have observed the electronic transitions within the ('4)T(,1g) ground state of Co('2+) in MgO by Raman spectroscopy. We identified the (GAMMA)(,6g) (--->) (GAMMA)(,8g)('1) transition at 305 cm('-1) and the (GAMMA)(,6g )(--->)(, )(GAMMA)(,8g)('2) transition at 930 cm('-1); the (GAMMA)(,6g )(--->)(, )(GAMMA)(,7g) transition is not seen and is lost in the two-phonon band. We also observed an impurity induced vibration mode at 280 cm('-1), in resonance with the acoustic phonon branches at the surface of the Brillouin zone. The position of the electronic levels cannot be explained by crystal field theory, with the spin-orbit interaction to second-order included. We have calculated the effect of a dynamical Jahn-Teller interaction and have shown, for the first time, the necessity to include the coupling to the T(,2g) mode, in addition to the coupling to the E(,g) mode, although Co('2+) in MgO is a weak Jahn-Teller system. / We also used Raman spectroscopy to observe the vibrational modes of (beta)-In(,2)Se(,2). We observed, for the first time, the layer to layer shear mode(E(,2g)('2)), at 19 cm('-1). The position of this peak and the others, at 42(E(,1g)('1)), 117(A(,1g)('1)), 179(E(,2g)('1)), 181(E(,1g)('2)) and 231 cm('-1)(A(,1g)('2)), follows the trend of the vibrational spectra of (beta)-Ga(,2)S(,2) and of (beta)-Ga(,2)Se(,2) {65}. Using the linear chain model, we calculated the shear force constants and deduced the position of the doublet (E(,2g)('1) and E(,1g)('2)) with very good agreement with the experimental values.

Ličio kobaltato (III)susidarymo ypatumai / PECULIARITYS OF LITHIUM COBALT OXIDE FORMATIONJakubianecienė, Miroslava 13 June 2005 (has links)
Lithium cobalt oxide was synthesized by solid-state reactions and SPRAY-DRY method. Its investigation of the formation were perform of lithium and cobalt acetate, lithium and cobalt citrate, LiOH and Co(NO3)2· 6H2O mixtures in high-temperatures. Their formation was analyzed and with the help of the X-ray diffraction the structure of the products of the solid-state reactions was determined. The thermal processes, that take place during the synthesis, were analyzed with the help of differential-thermal analysis.
