In this work, uniformly sized Cu2ZnSnS4 (CZTS) nanoparticles with easy control of chemical composition were synthesized and printable ink containing CZTS nanoparticles was prepared for low-cost solar cell applications. In addition, we studied the effects of synthesis conditions, such as reaction temperature and time, on properties of the CZTS nanoparticles. For CZTS nanoparticles synthesis process, the reactants were mixed as the 2:1:1:4 molar ratios. The reaction temperature and time was varied from 220C to 320C and from 3 hours to 5 hours, respectively. The crystal structure and morphology of CZTS nanoparticles prepared under the various conditions were investigated by X-ray diffraction (XRD) and field-emission scanning electron microscopy (FE-SEM), and energy dispersive X-ray spectroscopy (EDS) was used for compositional analysis of the CZTS nanoparticles.

The reactions of a series of 1,2,3,4-tetrahydropyridin-2-ones (1) with diazoacetates (2) in the presence of copper-bronze catalyst yielded exclusively 3-oxo-2-azabicyclo [4.1.0] heptanes (3 and 4) in excellent yields with high exo-selectivity. Tetrahydropyridin-2-ones (1) with N-alkyl substituents were found to be more reactive than N-aryl substitutents. Among the various copper catalysts studied, copper(II) triflate was found to be the best catalyst while rhodium chloride, ruthenium chloride did not catalyze the reaction. The application of ultrasonic radiation enhanced the reaction rate and allowed the reactions to be conducted at room temperature.

General principles of formation and stability of the heterometallic alkoxides existing due to Lewis Acid-Base interaction, isomorphous substitution and heterometallic metal-metal bonds are discussed. The molecular structure design approach based on the choice of a proper molecular structure type and completing it with the ligands, providing both the necessary number of donor atoms and the sterical protection of the metaloxygen core, is presented. Its applications in prediction of the composition and structure of single source precursors of inorganic materials are demonstrated for such classes of compounds as oxoalkoxides, alkoxide beta-diketonates, alkoxide carboxylates, derivatives of functional alcohols, metallatranes and metallasiloxanes.

The cyclohexene-derived aziridine 7-tosyl-7-azabicyclo[4.1.0]heptane (1) reacts with Grignard reagents in the presence of chiral nonracemic Cu-catalysts to afford sulfonamides 3a-e in up to 91% ee under optimized conditions. No activation of the aziridine by Lewis acids is required. The reaction may be extended to other bicyclic N-sulfonylated aziridines, but aziridines derived from acyclic olefins, cyclooctene, and trinorbornene are unreactive under standard conditions. Exposure of 1 to s-BuLi in the presence of (-)-sparteine (2.8 equiv.) affords the allylic sulfonamide 31 in 35% yield and 39% ee. Under the same conditions, the aziridines 33 and 35 yield products 34 and 36 derived from intramolecular carbenoid insertion with 75 and 43% ee, respectively.

Treatment of UCl4 with the hexadentate Schiff bases H 2L? in thf gave the expected [UL?Cl2(thf)] complexes [H2L? = N,N?-bis(3-methoxysalicylidene)-R and R = 2,2-dimethyl-1,3-propanediamine (i = 1), R = 1,3-propanediamine (i = 2), R = 2-amino-benzylamine (i = 3), R = 2-methyl-1,2-propanediamine (i = 4), R = 1,2-phenylenediamine (i = 5)]. The crystal structure of (UL4Cl 2(thf)] (4) shows the metal in a quite perfect pentagonal bipyramidal configuration, with the two Cl atoms in apical positions. Reaction of UCl 4 with H4L? in pyridine did not afford the mononuclear products [U(H2L?)Cl2(py)x] but gave instead polynuclear complexes [H4L? = N,N?-bis(3-hydroxysalicylidene)-R and R = 1,3-propanediamine (i = 6), R = 2-amino-benzylamine (i = 7) or R = 2-methyl-1,2-propanediamine (i = 8)]. In the presence of H4L6 and H4L7 in pyridine, UCl4 was transformed in a serendipitous and reproducible manner into the tetranuclear U(IV) complexes [Hpy]2[U 4(L6)2(H2L6) 2Cl6] (6a) and [Hpy]2[U4(L 7)2(H2L7)2Cl 6][U4(L7)2(H2L 7)2 Cl4(py)2] (7), respectively. Treatment of UCl4 with [Zn(H2L6)] led to the formation of the neutral compound [U4(L6) 2(H2L6)2Cl4(py) 2] (6b). The hexanuclear complex [Hpy]2[U 6(L8)4Cl10(py)4] (8) was obtained by reaction of UCl4 and H4L8. The centrosymmetric crystal structures of 6a·2HpyCl·2py, 6b·6py, 7·16py and 8·6py illustrate the potential of Schiff bases as associating ligands for the design of polynuclear assemblies.

Copper-sulfide nanocrystals can accommodate considerable densities of delocalized valence-band holes, introducing localized surface plasmon resonances (LSPRs) attractive for infrared plasmonic applications. Chemical control over nanocrystal shape, composition, and charge-carrier densities further broadens their scope of potential properties and applications. Although a great deal of control over LSPRs in these materials has been demonstrated, structural complexities have inhibited detailed descriptions of the microscopic chemical processes that transform them from nearly intrinsic to degenerately doped semiconductors. A comprehensive understanding of these transformations will facilitate use of these materials in emerging technologies. Here, we apply spectroelectrochemical potentiometry as a quantitative in situ probe of copper-sulfide nanocrystal Fermi-level energies (EF) during redox reactions that switch their LSPR bands on and off. We demonstrate spectroscopically indistinguishable LSPR bands in low-chalcocite copper-sulfide nanocrystals with and without lattice cation vacancies and show that cation vacancies are much more effective than surface anions at stabilizing excess free carriers. The appearance of the LSPR band, the shift in EF, and the change in crystal structure upon nanocrystal oxidation are all fully reversible upon addition of outer-sphere reductants. These measurements further allow quantitative comparison of the coupled and stepwise oxidation/cation-vacancy-formation reactions associated with LSPRs in copper-sulfide nanocrystals, highlighting fundamental thermodynamic considerations relevant to technologies that rely on reversible or low-driving-force plasmon generation in semiconductor nanostructures.

A macrocyclization-transannulation strategy is the crux of an efficient total synthesis of the benzolactone enamide apicularen A (see scheme; Bn = benzyl). Key steps include a four-component coupling, a Stille cross-coupling to introduce the aromatic moiety, and the formation of the enamide from a hemiaminal. The size-selective macrolactonization of the ethoxyvinyl ester shown was followed by transannular etherification in excellent yield.

The oxidation of white phosphorus by hydrogen peroxide or different organic peroxides (such as tert-butyl hydroperoxide, dibenzoylperoxide, 3-chloroperoxybenzoic acid) has been studied in both aqueous and alcoholic solutions under anaerobic conditions. Depending on the reaction conditions, P(I) (hypophosphorous acid), P(III) [phosphorous acid, mono- and dialkyl (or diaryl) hydrogen phosphonates] and P(V) [phosphoric acid or trialkyl (or triaryl) phosphates] derivatives are produced. The catalytic oxidative P-O coupling of P4 to water, aliphatic alcohols and phenol under mild reaction conditions is accomplished by using copper(I), copper(II) and vanadium(IV) complexes. Catalytic conversion of white phosphorus with complete efficiency and high selectivity for monoalkyl hydrogen phosphonates (>95%) may be achieved using 3-ClC6H4C(O)OOH as oxidant under optimized conditions. An identical radical mechanism is suggested to account for both the stoichiometric and the catalytic oxidative hydroxydation, alkoxydation and phenoxydation of white phosphorus promoted by peroxides in both aqueous biphasic conditions and organic solutions.
