  • Studies of the Structure, Amidicity, and Reactivity of N-Chlorohydroxamic
           Esters and N-Chloro-β,β-dialkylhydrazides: Anomeric Amides with
           Low Resonance Energies
    • Authors: Stephen A. Glover, Adam A. Rosser, Robert M. Spence
      Abstract: Stephen A. Glover, Adam A. Rosser, Robert M. Spence
      DFT with dispersion correction and expanded basis set computes N-chloro-N-dimethylaminoacetamide to be completely planar but with only 63 % the resonance energy of N,N-dimethylacetamide. N-chloro-N-methoxyacetamide has a much lower resonance (45 %) and it is pyramidal at nitrogen. These are unusual anomeric amides.

      Abstract: Lei Zhang, Ling-Yan Jiang, Ke Zheng, Hua Duan, Min Li, Yuan-Chen Cui
      An environmentally benign aqueous micelle system was successfully used as reaction medium to perform enzymatic polymerization of p-cresol. The structure of the resulting p-cresol oligomers is similar to that of polyphenolic compounds in natural plants. p-Cresol oligomers show good free radical scavenging activity and good prospects as novel antioxidant.

      Abstract: Rafael Fernández-Galán, Juan-Antonio Navarro, Fernando Carrillo-Hermosilla, Antonio Antiñolo, Isabel López-Solera, Elena Villaseñor
      Asymmetric guanidinate-supported zirconium complexes with different degrees of substitution can be easily prepared by reaction of the simple precursors ZrCl4 or [ZrCl2(η5-C5H5)2] with the corresponding lithium guanidinate salt, or by reaction of [Zr?κ2N,N′-(NEt)(N-t-Bu)CNMe2?2Cl2], obtained by insertion of carbodiimide into a Zr–amido bond, with NaC5H5.

      The use of guanidinate ligands for chemical vapour deposition (CVD) and atomic layer deposition (ALD) of thin films over the past 5 years is reviewed. Design trends for metal complexes, promising precursor candidates, and the future outlook for guanidinates in ALD and CVD are reported.

      Abstract: Peter Tutacz, Ronny Syre, Cristian G. Hrib, Liane Hilfert, Nancy Frenzel, Edmund P. Burte, Marcel Kühling, Frank T. Edelmann
      The first lithium-aziridinylamidinates, Li[(C2H4N)C(NR)2]·THF (R = iPr, Cy; iPr = isopropyl, Cy = cyclohexyl), have been prepared by addition of N-aziridinyllithium, C2H4NLi, to either N,N′-diisopropylcarbodiimide or N,N′-dicyclohexylcarbodiimide. In the solid state, these lithium-aziridinylamidinates comprise ladder-type dimeric molecular structures.

  • Effect of Intramolecular Hydrogen Bonds on the Gas-Phase Basicity of
           Guanidines
    • Authors: Zoran Glasovac, Mirjana Eckert-Maksić
      Abstract: Zoran Glasovac, Mirjana Eckert-Maksić
      Predicting acid/base properties of unknown molecules using data which can be tabulated is an everlasting goal in chemistry. In this sense, molecules containing intramolecular hydrogen bond are especially problematic. Our results show very good correlation of GB against pKHB and newly introduced σ4B parameter for a series of guanidine bases with intramolecular hydrogen bond.

  • Synergistic Antibacterial Activity of Nanohybrid Materials ZnO–Ag
           and ZnO–Au: Synthesis, Characterization, and Comparative Analysis
           of Undoped and Doped ZnO Nanoparticles
    • Authors: Adriana Berenice Pérez Jiménez, Carlos Alberto Huerta Aguilar, Jorge Manuel Vázquez Ramos, Pandiyan Thangarasu
      Abstract: Adriana Berenice Pérez Jiménez, Carlos Alberto Huerta Aguilar, Jorge Manuel Vázquez Ramos, Pandiyan Thangarasu
      Because ZnO and Ag nanoparticles (NPs) effectively inhibit foodborne pathogens, both metals are expected to produce a more effective inhibitor as a result of hybrid properties. It has been reported that Ag-doped ZnO NPs and ZnO NPs do not show much difference in antibacterial activities, but show an increase in bacterial inhibition. To explain why doping of Ag NPs, unlike Au NPs, in ZnO NPs influences the antibacterial activities, ZnO, ZnO–Ag, and ZnO–Au NPs were synthesized.

           Superbases

      Abstract: Vjekoslav Štrukil, Edislav Lekšić, Ernest Meštrović, Mirjana Eckert-Maksić
      A synthetic approach towards peralkylated triguanide superbases based on a coupling reaction between a Vilsmeier salt and monosubstituted guanidines is described. Single crystal X-ray diffraction enabled the first structural characterization of benzyloctamethyl derivative, which was also evaluated as a potential organocatalyst in the transesterification reaction of vegetable oil.

      A novel ligand, N-(8-quinolyl)-5-tert-butylsalicylaldimine (Hqsal-5-tBu) is prepared and a series of FeIII complexes, [FeIII(qsal-5-tBu)2]+ studied. Strong structural distortions caused by the ligand result in the complexes becoming trapped in the high spin state.

      Abstract: Christoph Krämer, Ute Wild, Olaf Hübner, Christiane Neuhäuser, Elisabeth Kaifer, Hans-Jörg Himmel
      The redox-active guanidine-functionalized 1,2,4,5-tetrakis(N,N’-diisopropylguanidino)benzene was recently shown to be a redox-active switch, and reversibly forms hydrogen-bond aggregates upon two-electron oxidation. In this work, the hydrogen-bond motifs in the first coordination compounds with the neutral and oxidized guanidine as ligand are reported.

      A highly efficient method for the conversion of tosylates into the corresponding iodides is outlined, involving heating a neat mixture of tosylates and sodium iodide in a microwave cavity. This procedure is especially useful for the in situ generation of volatile primary iodides.

  • Probing Mechanisms of Aryl–Aryl Bond Cleavages under Flash Vacuum
           Pyrolysis Conditions
    • Authors: Edward A. Jackson, Xiang Xue, Hee Yeon Cho, Lawrence T. Scott
      Abstract: Edward A. Jackson, Xiang Xue, Hee Yeon Cho, Lawrence T. Scott
      Flash vacuum pyrolysis (FVP) of phenyl-substituted polycyclic aromatic hydrocarbons (PAHs) promotes the formation of new rings by thermal cyclodehydrogenation reactions; however, such reactions are often accompanied by competitive loss of the phenyl group. Such ‘phenyl loss’ reactions cleave strong aryl–aryl bonds and are therefore important to understand. As probes for the mechanism(s) involved in the ‘phenyl loss’ reaction, FVP experiments were conducted with several phenyl-substituted PAHs and larger biaryls.

           Cyclodehydrogenation Reactions in Polycyclic Aromatic Hydrocarbons
    • Authors: Aaron W. Amick, Sara E. Martin
      Abstract: Aaron W. Amick, Sara E. Martin
      Flash vacuum pyrolysis (FVP) has become an integral part of the synthesis of both flat and curved polycyclic aromatic hydrocarbons (PAHs). We report a new process to facilitate the cyclodehydrogenation of PAHs using an external radical source. This process has been shown to greatly increase the conversion of PAHs to their cyclodehydrogenated products.

    • Authors: Paul Malek Mirzayans, Elizabeth H. Krenske, Craig M. Williams
      Abstract: Paul Malek Mirzayans, Elizabeth H. Krenske, Craig M. Williams
      NAY SAYers. Those wishing to utilise nonstabilised azomethine ylids have the right to complain about reaction condition choice. Higher temperature conditions predominate over lower temperature conditions, which limits the application of azomethine cycloadditions to robust dipolarophiles. We present a mechanistic analysis of the application of the Roussi reaction for low-temperature generation of nonstabilised azomethine ylids to the challenging substrate N-methylmorpholine N-oxide.

      Abstract: Wuji Sun, Yangye Jiang, Hong Yan, Xiuqing Song
      A series of 2-amino-3-cyano-4-aryl-4H-pyrans were synthesised by reacting malononitrile, ethyl acetoacetate and aromatic aldehydes under ultrasound irradiation. The photoreaction of 2-amino-3-cyano-4-aryl-4H-pyrans were tested in conventional solvents to generate the 1,3-butadienes under irradiation with UV light. The 1,3-butadiene structures were determined by 1H and 13C NMR spectra, high-resolution mass spectrometry, and single crystal X-ray diffraction analysis.
