Copper-Catalyzed Cross-Coupling of Silicon Pronucleophiles with Unactivated Alkyl Electrophiles Coupled with Radical Cyclization

A copper-catalyzed C(sp3)-Si cross-coupling of aliphatic C(sp3)-I electrophiles using a Si-B reagent as the silicon pronucleophile is reported. The reaction involves an alkyl radical intermediate that also engages in 5-exo-trig ring closures onto pendant alkenes prior to the terminating C(sp3)-Si bond formation. Several Ueno-Stork-type precursors cyclized with excellent diastereocontrol in good yields. The base-mediated release of the silicon nucleophile and the copper-catalyzed radical process are analyzed by quantum-chemical calculations, leading to a full mechanistic picture.

Two distinct Cu(I) coordination polymers based on isoniazid and different bridged groups

Two coordination polymers of [CuSCN(INH)] n (1) and [CuCl(INH)] n (2) have been synthesized (where INH = isoniazid). Their crystal structures have been determined by X-ray single crystal diffraction and both of them belong to monoclinic system. The Cu(I) ions in 1 and 2 all adopt distorted tetrahedral geometries. The complex 1 belongs to Cc space group and the cell parameters are: a = 44.370(2) A, b = 3.811(3) A, c = 30.2800(19) A, beta = 132.87(3) and Z = 4. The Cu(I) ion in 1 is coordinated to three SCN groups and one INH ligand and such coordination model result in a 2D networks construction. Complex 2 crystallizes in the P21/c space group and the cell parameters are: a = 7.0319(13) A, b = 18.367(3) A, c = 6.0644(11) A, beta = 93.466(2) and Z = 4. Each copper atom in 2 is ligated by two INH ligands and two chlorine groups. Two copper atoms are asymmetrically bridged by two chlorine ligands to form a Cu2Cl 2 unit. Each Cu2Cl2 fragment is bridged by four INH groups to form a 2D layer structure.

Vibrational Relaxation Dynamics of a Semiconductor Copper(I) Thiocyanate (CuSCN) Film as a Hole-Transporting Layer

The semiconductor CuSCN film, which is typically used as the hole-transporting layer (HTL) in solar cell studies, has been investigated by Fourier transform infrared (FTIR) spectroscopy and ultrafast transient infrared (IR) spectroscopy. A sharp peak at 2175 cm-1 corresponding to the CN vibrational stretching mode in CuSCN was observed, and the peak frequency remained unchanged by varying the thickness of the CuSCN thin film. Vibrational relaxation measurements showed that the 0-1 and 1-2 transitions of CN stretching can be observed at 2175 and 2140 cm-1, respectively. The heat-induced absorption and bleaching peaks (2167 and 2175 cm-1) can be clearly seen at a waiting time of 40 ps. The vibrational relaxation of the CN stretching mode determined from the 1-2 transition exhibited a biexponential decay with time constants of 7.4 ¡À 0.5 (90%) and 158 ¡À 50 ps (10%). Importantly, the abnormal anisotropy decay of the CN stretching mode in the CuSCN thin film was also observed for the first time. A detailed analysis showed that the distinct anisotropy decay curve could be described using a triexponential decay function, which was explained by three different processes: Resonance energy transfer (?8 ps), a thermalization process (?40 ps), and molecular rotation (?150 ps). The time scale of the thermalization process caused by the vibrational relaxation in CuSCN is at a time scale of 40 ps, which is important for us to understand the thermally activated charge-transport property of the CuSCN film employed as the HTL. Further UV pump-IR probe measurement revealed that the carrier scattering and relaxation processes in the CuSCN film are strongly associated with the vibrational excitation and relaxation dynamics of the CN stretching mode. It is expected that the fundamental understanding of the vibrational relaxation dynamics of the CuSCN thin film should provide helpful insight to elucidate its role as the HTL in solar cell studies at the molecular level.

Copper-catalyzed stereoselective aminoboration of bicyclic alkenes

A copper-catalyzed aminoboration of bicyclic alkenes, including oxa- and azabenzonorbornadienes, has been developed. With this method, amine and boron moieties are simultaneously introduced at an olefin with exo selectivity. Subsequent stereospecific transformations of the boryl group can provide oxygen- and nitrogen-rich cyclic molecules with motifs that may be found in natural products or pharmaceutically active compounds. Moreover, a catalytic asymmetric variant of this transformation was realized by using a copper complex with a chiral bisphosphine ligand, namely (R,R)-Ph-BPE.

Solution-processed p-type copper(I) thiocyanate (CuSCN) for low-voltage flexible thin-film transistors and integrated inverter circuits

We report on low operating voltage thin-film transistors (TFTs) and integrated inverters based on copper(I) thiocyanate (CuSCN) layers processed from solution at low temperature on free-standing plastic foils. As-fabricated coplanar bottom-gate and staggered top-gate TFTs exhibit hole-transporting characteristics with average mobility values of 0.0016 cm2 V?1 s?1 and 0.013 cm2 V?1 s?1, respectively, current on/off ratio in the range 102-104, and maximum operating voltages between ?3.5 and ?10 V, depending on the gate dielectric employed. The promising TFT characteristics enable fabrication of unipolar NOT gates on flexible free-standing plastic substrates with voltage gain of 3.4 at voltages as low as ?3.5 V. Importantly, discrete CuSCN transistors and integrated logic inverters remain fully functional even when mechanically bent to a tensile radius of 4 mm, demonstrating the potential of the technology for flexible electronics.

Microstructures, optical and photovoltaic properties of CH3NH3PbI3(1-x)Clx perovskite films with CuSCN additive

Microstructures, optical and photovoltaic properties of CH3NH3PbI3(1-x)Clx perovskite films with copper(I) thiocyanate (CuSCN) additive were investigated. The CuSCN-added CH3NH3PbI3(1-x)Clx films were prepared by a hot air blow-assisted spin-coating method. Current density-voltage characteristics of the photovoltaic device using the CuSCN-added CH3NH3PbI3(1-x)Clx light-absorbing layer showed increases in short-circuit current density, open-circuit voltage, which resulted in increase in the conversion efficiency. Microstructure analysis showed that the crystal structure of the CuSCN-added CH3NH3PbI3(1-x)Clx was a pseudocubic system. From these results, partial substitutions of Pb2+ and anions (I- and Cl-) by Cu ions (Cu+ and Cu2+) and SCN-, respectively, are considered to occur in the CuSCN-added CH3NH3PbI3(1-x)Clx films. Based on the obtained results, reaction mechanisms of the CH3NH3PbI3(1-x)Clx films with and without CuSCN additive were discussed.

Trinuclear-based copper(I) pyrazolate polymers: Effect of trimer pi-acid¡¤ ¡¤ ¡¤halide/pseudohalide interactions on the supramolecular structure and phosphorescence

Under different situations, solvothermal reactions of 3,5-diethyl-4-(4- pyridyl)-pyrazole (HL) with CuX or CuX2 (X = Cl, Br, I, and SCN) afforded five copper(I) coordination polymers, {CuX[CuL]3¡¤ solvent}n (X = Cl, 1; Br, 2; I, 3; X = SCN and solvent = MeCN, 4) and {Cu2I2[CuL]3}n (5). X-ray diffraction analyses show that all the complexes have trinuclear [CuL] 3 (referred as Cu3) secondary building units featuring planar nine-membered Cu3N6 metallocycles with three peripheral pyridyl groups as connectors, which are further linked by CuX or Cu2X2 motifs to generate single- or double-strand chains. Interestingly, the Cu(I) atoms within the Cu3 units in 1-5 behave as coordinatively unsaturated pi-acid centers to contact soft halide/pseudohalide X atoms of CuX and Cu2X2 motifs, which lead to novel sandwich substructures of [(Cu3)(Cu2X2)(Cu 3)] (X = Br, I, and SCN) in 2-4. In addition, both the pi-acid [Cu3]¡¤¡¤¡¤X contacts and intertrimer Cu¡¤¡¤¡¤Cu interactions contribute to the one-dimensional (1D) double-strand and 2D/3D supramolecular structures of 1-5. All of these complexes exhibit high thermostability and bright solid-state phosphorescence upon exposure to UV radiation at room temperature. The emissions arise from the mixtures of metal-centered charge transfer, metal to ligand charge transfer, and halide-to-ligand charge transfer excited states, and can be tuned by intermolecular pi-acid [Cu3]¡¤¡¤¡¤halide/ pseudohalide contacts.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! Read on for other articles about Application of 1111-67-7!, Safety of Cuprous thiocyanate
