We describe the synthesis of novel mononuclear and dinuclear copper complexes and an investigation of their behaviour in solution using mass spectrometry (ESI-MS and ESI-MS/MS) and in the solid state using X-ray crystallography. The complexes were synthesized from two widely used diacetylpryridine (dap) ligands, i.e. 2,6-diacetylpyridinebis(benzoic acid hydrazone) and 2,6-diacetylpyridinebis(2-aminobenzoic acid hydrazone). Theoretical calculations (DFT) were used to predict the complex geometries of these new structures, their equilibrium in solution and energies associated with the transformations.

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.

A straightforward synthesis of the zwitterionic benzoquinonemonoimine 8 is reported. This molecule is a rare example of a zwitterion being more stable than its canonical forms. It is shown that 8 is best described as constituted of two chemically connected but electronically not conjugated 6 pi electron subunits. Its reactivity with electrophiles such as H+, CH3+, and metal salts leads to the synthesis of new 12 pi electron molecules 12 (H +), 14 (CH3+), and 20 (pd2+), respectively, in which one or both 6 pi electron subsystems localize into an alternation of single and double bonds, as established by X-ray diffraction. The acidity of the N-H protons of 8 can be modulated by an external reagent. Dependent on the electrophile used, the control of the pi system delocalization becomes possible. When the electrophile simply adds to the zwitterion as in 12, 14, or 15, there is no more negative charge to be delocalized and only the positive charge remains delocalized between the nitrogen atoms. Furthermore, when a reaction with the electrophilic reagent results in deprotonation, as in 17-21, there remains no charge in the system to be delocalized. DFT calculations were performed on models of 8, 12, 14, 20, and on other related zwitterions 9 and 10 in order to examine the influence of the fused cycles on the charge separation and on the singlet-triplet energy gap. An effect of the nitrogen substituents in 8 is to significantly stabilize the singlet state. The dipole moment of 8 was measured to be 9.7 D in dichloromethane, in agreement with calculated values. The new ligands and complexes described in this article constitute new classes of compounds relevant to many areas of chemistry.

The reactions of salicylaldehyde oxime (H2salox) with Cu II precursors yielded the known complexes [Cu(Hsalox)2] (1) and [Cu(Hsalox)2]n (2), as well as complexes [Cu 3(salox)(L1)(L2)]·MeCN (3·MeCN), [CuCl(L1)] (4) and [Cu2Na(O2CMe) 5(HO2CMe)]n (5), where L1 – = o-O-C6H4-CHNO-C(CH3)NH and L23- = o-O-C6H4-CHNO-C(o-O-C 6H4)N. L1- was formed in situ via the nucleophilic addition of the oximato O-atom of salox2- to the unsaturated nitrile group of the MeCN reaction solvent. L2 3- is also formed in situ probably through the nucleophilic attack of the oximato O-atom to the unsaturated nitrile group of salicylnitrile; the latter, although not directly added to the reaction mixture, can be produced via the dehydration of salox2-. Compounds 1 and 2 contain Hsalox – bound to the metal center in two different coordination modes; they both contain the same mononuclear unit, however a 2D network is generated in 2 due to a relatively long Cu-Ooximato bond. Compound 3 contains three different ligands, i.e. salox2-, L1- and L 23-, which act as mu3-kappa2O: kappaO?:kappaN, kappaO:kappaN:kappaN? and mu3-kappa2O:kappa2N:kappaO?: kappaN?, respectively, whereas 4 consists of a square planar Cu II atom bound to a kappaO:kappaN:kappaN? L 1- and a chloride ion. Compound 5 consists of dinuclear [Cu2(O2CMe)5(HO2CMe)]- units and Na+ ions assembled into an overall 3D network structure. Magnetic susceptibility measurements from polycrystalline samples of 2 and 5 gave best-fit parameters J = +0.36 cm-1 (H = -JS? iS?j) and J = -360 cm-1, zj = +20 cm -1 (H = -JS?iS?j – zJ?S z?S?z), respectively.

Despite its industrial importance, very limited mechanistic information on the dehydrogenative coupling of dimethyl phthalate has been reported. Herein we report the detailed mechanism for dehydrogenative coupling of dimethyl phthalate catalyzed by [Pd(OAc)2]/[Cu(OAc)2]/1,10-phenanthroline·H2O (phen·H2O). The solution-phase analysis of the catalytic system by XANES shows the active species to be Pd(II), and EXAFS supports the formation of an (acetato)(dimethyl phthalyl)(phen)palladium(II) complex from [Pd(OAc)2]. A formation pathway of tetramethyl 3,3?,4,4?-biphenyltetracarboxylate via disproportionation of independently prepared [Pd(OAc){C6H3(CO2Me)2-3,4}(phen)] is observed with regeneration of [Pd(OAc)2(phen)].

We report the cyclohexene oxidation by molecular oxygen in the presence of several metal beta-diketonates. The catalytic conditions used showed an allylic/vinilic oxidation (ao/av) ratio equal 1.5. The complexes M(l)n were used with the metal ions Co(III), Ni(II), Pd(II), Cu(II), chelated with acetylacetone (AcAc), benzoylacetone (BeAc) and dibenzoylacetone (BeBe) as ligands. The oxidation selectivity of the studied system suggests a different allylic/vinylic pathway compared with that observed inprevious reports.

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.
