Synthesis of Co9S8, Ni3S2, Co and Ni nanowires by solventless thermolysis of a mixture of metal(ii) acetate and cysteine in vacuum is reported. The simple precursor system enables the nanowire phase to be tuned from pure metal (Co or Ni) to metal sulfide (Co9S8, Ni3S2) by varying the relative concentration of the metal(ii) acetate. The growth environment facilitates new insights through in situ characterization using field-emission scanning electron microscopy (FESEM) and thermogravimetric analysis with gas chromatography-mass spectrometry (TGA-GC-MS). Direct observation by FESEM shows the temperature at which nanowire growth occurs and suggests adatoms are incorporated into the base of the growing nanowire. TGA-GC-MS reveals the rates of precursor decomposition and identity of the volatilized ligand fragments during heat-up and at the nanowire growth temperature. Our results constitute a new approach for the selective fabrication of high quality Co9S8 and Ni3S2 nanowires and more importantly provides new understanding of precursor decomposition reactions that support symmetry-breaking growth in nanocrystals by heat-up synthesis.

Networks of C–H⋯S interactions have been discovered within the molecular structure of sodium di-(isopropyl)dithiocarbamate pentahydrate with the formula Na(C7H14NS2)·5H2O, revealed by single crystal X-ray diffraction. These interactions have also been investigated by ab initio and Hirshfeld surface analyses which show that the electron density is not symmetrical about the molecule. NMR spectroscopy in solution and solid the state showed temperature dependent restricted rotation of the isopropyl groups, which is attributed to the intramolecular C–H⋯S interactions. The ubiquitous nature of C–H⋯S intramolecular interactions in this class of compound is evident in the structures of other di-(isopropyl)dithiocarbamate complexes deposited in the CSD. In general, the restricted rotation in di-(isopropyl)dithiocarbamate complexes can be directly attributed to intramolecular C–H⋯S interactions, which subsequently influence the geometry in association with steric repulsion factors.

Abstract The molecular structure of bis(κ2S,Sʹ-di(isopropyl)dithiocarbamato)nickel(II) has been examined by single crystal X-ray diffraction. The data reveal a C–H⋅⋅⋅Ni anagostic interaction arising from the interaction of two non-equivalent molecules within the crystal. Thermal analysis data show that the complex decomposes at ∼330 °C. The structure of the resultant NiS material was examined using scanning electron microscopy and energy dispersive X-ray spectroscopy which revealed NiS nanowires.

An effective method for synthesising alkaloidlike compounds containing the 3-azabicyclo[3.3.1]non-3-ene core structure was successfully carried out in a stereoselective manner via the bridged-Ritter reactions. Important optically active 6-alkyl(aryl)amido-4-alkyl( aryl)-2,2,6-trimethyl-3-azabicyclo[3.3.1]non-3-enes (imino amides) and 4-alkyl(aryl)-2,2,6-trimethyl-3-azabicyclo[3.3.1]nona-3,6-dienes (imino alkenes) were obtained in one step from (-)-b-pinene and the respective nitriles in the presence of concentrated H2SO4. The relative compositions of these products were controlled by varying the reaction conditions. Kinetic studies were conducted to enable a mechanistic understanding of the reaction pathways.
