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.

The understanding of the photochemical charge transfer properties of powdered semiconductors is of relevance to artificial photosynthesis and the production of solar fuels. Here we use surface photovoltage spectroscopy to probe photoelectrochemical charge transfer between bismuth vanadate (BiVO4) and cuprous oxide (Cu2O) particles as a function of wavelength and film thickness. Optimized conditions produce a -2.10 V photovoltage under 2.5 eV (0.1 mW cm-2) illumination, which suggests the possibility of a water splitting system based on a BiVO4-Cu2O direct contact particle tandem.

Liquid-phase oxidation of 3,5-di-tert-butylcatechol (3,5-DtBC) by molecular oxygen was carried out in the presence of homogeneous Cu(II) chelates or heterogeneous Cu(II)-poly(4-vinylpyridine) (Cu(II)-PVP) catalytic systems. The oxidation product in both cases is 3,5-di-tert-butyl-o-benzoquinone (3,5-DtBQ). The catalytic activity of the oxidation of 3,5-DtBC catalyzed by the homogeneous Cu(II) system was found to be affected by the Cu(II) chelates used as the catalyst, the addition of pyridine derivatives, and their amounts added. The oxidation activity was found to increase with the basicity of the added pyridine derivatives. The kinetic data obtained from the formation rate of 3,5-DtBQ by the homogeneous bis(acetylacetonato)Cu(II)-pyridine catalytic system showed that the rate was independent of the 3,5-DtBC concentration, second order in the concentration of the catalyst, and first order with respect to the partial pressure of oxygen. The homogeneous copper(II) chelate-catalyzed oxidation of 3,5-DtBC confirmed the stoichiometric equation 3,5-DtBC + 1 2O2 = 3,5-DtBQ + H2O. On the basis of these data, possible mechanistic interpretations are discussed, in which a dimeric Cu(II) complex is assumed to be the active species. The kinetics of 3,5-DtBC oxidation by molecular oxygen in the presence of the heterogeneous Cu(II)-PVP catalyst revealed that both the oxygen absorption rate and effectiveness factor decreased with increasing particle size of the Cu(II)-PVP catalyst. The increase of the particle size of the catalyst was found to cause an increase in the fraction of mass transfer resistance in the total (mass transfer + reaction) resistance of the oxidation reaction.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.

A variety of metal salts have been found to undergo reduction by thermal and photochemical interaction with tetraarylborate salts and with neutral alkyl- and aryl-borane complexes.In the cases of Cu2+, Cu+, Ni2+, Co2+, Pd2+, Pt2+, Ag+, Zn2+, Hg2+, Sn2+, Pb2+ and Rh3+ salts, such photochemical reductions with NaBPh4 led to the deposition of the free metal, while a number of binary mixtures of metal salts led to the codeposition of both metals, sometimes as true alloys, under such photoreduction.In the course of these reductions the arylboratereductants underwent oxidative coupling of the aryl groups to form biaryls in a strictly intra-ionic (for BAr4-) or intramolecular (Ar3B) manner respectively.Individual studies of the photochemistry of the tetraarylborate anion itself, of cuprous tetraphenylborate and of the triphenylborane-pyridine complex have adduced evidence for a gamut of reactive intermediates capable of serving as the photoreductant for metal ions, such as triarylborane radical anions, diarylborate(I) anions or arylborenes, 7-borabicycloheptadiene anions or neutral complexes and finally arylborohydride anions or arylboron hydrides.The role of these intermediates both in the photoinduced skeletal rearrangements of arylboranes and in the concomitant reduction of metal ions is discussed in critical detail.Key words: Boron; Aryl; Oxidation; Copper; Nickel; Zinc

The electronic structures of Ni(II) and Cu(II) bis(acetylacetonates) and some of their gamma-substituted analogues (X = Cl, Me) are studied by photoelectron spectroscopy (PES). The vertical ionization energies of the compounds are determined, and the spectra are interpreted based on the trends of changes in the electronic structure and photoelectron spectra of acetylacetonates upon gamma-substitution. The suggested interpretation of the photoelectron spectra is confirmed by the quantum chemical INDO calculations of the electronic structure of the Cu(II) compounds.

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.

A coupled-perturbed Kohn-Sham treatment for the calculation of hyperfine tensors has been implemented into the MAG-ReSpect program. It treats spin-orbit contributions to hyperfine tensors by a combination of accurate and efficient approximations to the one- and two-electron spin-orbit Hamiltonians: (a) by the all-electron atomic mean-field approximation, and (b) by spin-orbit pseudopotentials. In contrast to a previous implementation, the code allows the use of hybrid functionals and lifts restrictions in the orbital and auxiliary basis sets that may be employed. Validation calculations have been performed on various transition metal complexes, as well as on a series of small diatomic molecules. In the case of a series of copper(II) complexes, the spin-orbit contributions are large, and their inclusion is essential to achieve agreement with experiment. Calculations with spin-orbit pseudopotentials allow the efficient simultaneous introduction of scalar relativistic and spin-orbit effects in the case of light nuclei in the neighborhood of heavy atoms.
