  1. Vibrational spectra, conformational properties and argon matrix photochemistry of diacetyl diselenide, CH3C(O)Se2C(O)CH3

    Bis(acetyl)diselenide ▪ CH3C(O)Se▪2 was prepared for the first time. Molecular characterization was performed by GC-MS, FTIR, FTRaman and Ar-matrix isolation-photochemistry experiments, in conjunction with DFT and ab-initio calculations. Gas phase composition at 298K was presented as a conformational equilibrium between two structures: a(C2) and b(C1). Major stability of conformer C2 was rationalized by means of hyperconjugative interactions involving nO, nSe, ▪ CO, ▪ *C-C, and ▪ *SeC orbitals. UV-vis photolysis of molecule trapped in solid argon brings about H2CCO, OCSe and CH3SeH.

  2. Quantification of the nucleophilic reactivity of nicotine

    The pyridine ring in nicotine reduces the nucleophilicity and Lewis basicity of the pyrrolidine nitrogen to such an extent that benzhydrylium ions react selectively at the pyridine nitrogen of nicotine.

  3. Solvent network at the transition state in the solvolysis of hindered sulfonyl compounds

    Mykyta Iazykov, Ludmila Rublova, Moisés Canle L. and J. Arturo Santaballa

    Mechanistic details of X-ArSO2Cl solvolytic processes at sulphur are discussed. Reaction order increases with the molecular volume of the nucleophile and is not related uniquely to the electronic nature of the X group. Alcoholysis is SN2 with cyclic (unbranched alcohols) or linear (branched alcohols) TSs involving a solvent network that mimics a general base catalysis process.

  4. Halogen bonding in biological context: a computational study of D2 dopamine receptor

    Halogen Bond (X-bond) interactions formed by halogenated ligands (LX) at the Dopamine Receptor D2 binding pocket (DRD2) were studied by Molecular Dynamics (MD) and charge density (QTAIM) analysis. The X-bonds were contrasted with the Hydrogen Bond (H-bond) interactions established by hydroxylated analogs (LOH, where X was replaced by OH). The results suggest a possible role of the X-bond as a protein secondary structure modulator because of the ability of the halogen to interact with the protein backbone.

  5. Lipase catalysed conversion of triglycerides to amides in liquid ammonia
