Electrodeposition of Crystalline Gallium‐Doped Germanium and SixGe1−x from an Ionic Liquid at Room Temperature
Authors: Lahiri Abhishek , Olschewski Mark , Carstens Timo , El Abedin Sherif Zein , Endres Frank 
Published: January 2015

AbstractIn this paper, we show the electrodeposition of both gallium‐doped crystalline germanium and SixGe1−x directly on copper at room temperature from an ionic liquid. Germanium and SixGe1−x were electrodeposited on a thin layer of electrodeposited gallium on copper, thereby leading to the formation of crystalline gallium‐doped germanium and SixGe1−x. From the microstructure, it appears that Ge and SixGe1−x dissolve in Ga to form an amalgam, which then recrystallises to form a crystalline structure. X‐ray diffraction confirmed the formation of crystalline phases. The indirect band gap of the gallium‐doped germanium measured by using scanning tunnelling spectroscopy is (0.9±0.1) eV.
Palladium‐Catalyzed Direct C2‐Arylation of an N‐Heterocyclic Carbene: An Atom‐Economic Route to Mesoionic Carbene Ligands
Authors: Ghadwal Rajendra S. , Reichmann Sven O. , Herbst‐Irmer Regine 
Published: January 2015

AbstractBlocking the C2 position of an imidazole‐derived classical N‐heterocyclic carbene (NHC) with an aryl group is an essential strategy to establish a route to mesoionic carbenes (MICs), which coordinate to the metal via the C4 (or C5) carbon atom. An efficient catalytic route to MIC precursors by direct arylation of an NHC is reported. Treatment of 1,3‐bis(2,6‐diisopropylphenyl)imidazol‐2‐ylidene (IPr) with an aryl iodide (RC6H4I) in the presence of 0.5 mol % of [Pd2(dba)3] (dba=dibenzylideneacetone) precatalyst affords the C2‐arylated imidazolium salts {IPr(C6H4R)}I (R=H, 4‐Me, 2‐Me, 4‐OMe, 4‐COOMe) in excellent (up to 92 %) yields. Treatment of {IPr(C6H5)}I with CuI and KN(SiMe3)2 exclusively affords the MIC–copper complex [(IPrPh)CuI].
Promotion of Double‐Duplex Invasion of Peptide Nucleic Acids through Conjugation with Nuclear Localization Signal Peptide
Authors: Aiba Yuichiro , Honda Yuta , Komiyama Makoto 
Published: January 2015

AbstractPseudo‐complementary peptide nucleic acid (pcPNA), as one of the most widely used synthetic DNA analogues, invades double‐stranded DNA according to Watson–Crick rules to form invasion complexes. This unique mode of DNA recognition induces structural changes at the invasion site and can be used for a range of applications. In this paper, pcPNA is conjugated with a nuclear localization signal (NLS) peptide, and its invading activity is notably promoted both thermodynamically and kinetically. Thus, the double‐duplex invasion complex is formed promptly at low pcPNA concentrations under high salt conditions, where the invasion otherwise never occurs. Furthermore, NLS‐modified pcPNA is successfully employed for site‐selective DNA scission, and the targeted DNA is selectively cleaved under conditions that are not conducive for DNA cutters using unmodified pcPNAs. This strategy of pcPNA modification is expected to be advantageous and promising for a range of in vitro and in vivo applications.
Is PdII‐Promoted σ‐Bond Metathesis Mechanism Operative for the PdPEPPSI Complex‐Catalyzed Amination of Chlorobenzene with Aniline? Experiment and Theory
Authors: Wang Feiqun , Zhu Lei , Zhou Yunfei , Bao Xiaoguang , Schaefer Henry F. 
Published: January 2015

AbstractReduction of the PdPEPPSI precatalyst to a Pd0 species is generally thought to be essential to drive Buchwald–Hartwig amination reactions through the well‐ documented Pd0/PdII catalytic cycle and little attention has been paid to other possible mechanisms. Considered here is the PdPEPPSI‐catalyzed aryl amination of chlorobenzene with aniline. A neat reaction system was used in new experiments, from which the potentially reductive roles of the solvent and labile ligand of the PEPPSI complex in leading to Pd0 species are ruled out. Computational results demonstrate that anilido‐containing PdII intermediates involving σ‐bond metathesis in pathways leading to the diphenylamine product have relatively low barriers. Such pathways are more favorable energetically than the corresponding reductive elimination reactions resulting in Pd0 species and other putative routes, such as the PdII/PdIV mechanism, single electron transfer mechanism, and halide atom transfer mechanism. In some special cases, if reactants/additives are inadequate to reduce a PdII precatalyst, a PdII‐involved σ‐bond metathesis mechanism might be feasible to drive the Buchwald–Hartwig amination reactions.
