      Konstantinova, Lidia S.; Bobkova, Irina E.; Nelyubina, Yulia V.; Chulanova, Elena A.; Irtegova, Irina G.; Vasilieva, Nadezhda V.; Sanz Camacho, Paula; Ashbrook, Sharon Elizabeth Marie; Hua, Guoxiong; Slawin, Alexandra Martha Zoya; Woollins, J Derek; Zibarev, Andrey V.; Rakitin, Oleg A. (2015-09) - Journal article
      Synthesis of 3,4-disubstituted and fused 1,2,5-selenadiazolo[3,4-b]pyrazines via previously unknown 3,4-diamino-1,2,5-selenadiazole has been achieved in moderate to high yields. The compounds synthesized were characterized ...

      Knight, Fergus Ross; Diamond, Louise; Athukorala Arachchige, Kasun Sankalpa; Sanz Camacho, Paula; Randall, Rebecca Amy Michele; Ashbrook, Sharon Elizabeth Marie; Buehl, Michael; Slawin, Alexandra Martha Zoya; Woollins, J Derek (2015-02-23) - Journal article
      Three related series of peri-substituted bis(tellurides) bearing naphthalene, acenaphthene and acenaphthylene backbones [Nap/Acenap/Aceyl(TeY)2 (Nap = naphthalene-1,8-diyl N; Acenap = acenaphthene-5,6-diyl A; Aceyl = ...
    • Direct synthesis of fused 1,2,5-selenadiazoles from 1,2,5-thiadiazoles 

      Konstantinova, Lidia S.; Knyazeva, Ekaterina A.; Nefyodov, Andrey A.; Sanz Camacho, Paula; Ashbrook, Sharon Elizabeth Marie; Woollins, J Derek; Zibarev, Andrey V.; Rakitin, Oleg A. (2015-02) - Journal article
      A short and convenient synthesis of fused 1,2,5-selenadiazoles from corresponding 1,2,5-thiadiazoles and selenium dioxide has been developed.
    • Investigating unusual homonuclear intermolecular “through-space” J couplings in organochalcogen systems 

      Sanz Camacho, Paula; McKay, David; Dawson, Daniel M.; Kirst, Chistin; Yates, Jonathan R.; Green, Timothy F. G.; Cordes, David B.; Slawin, Alexandra M. Z.; Woollins, J. Derek; Ashbrook, Sharon E. (2016-11-07) - Journal article
      Although the electron-mediated spin-spin or J coupling is conventionally viewed as transmitted via covalent bonds, examples of J couplings between atoms that are not formally bonded but are in close proximity (termed ...
    • Peri-substituted phosphorus-tellurium systems – an experimental and theoretical investigation of the P∙∙∙Te through-space interaction 

      Nordheider, Andreas; Hupf, Emanuel; Chalmers, Brian Alexander; Knight, Fergus Ross; Buehl, Michael; Mebs, Stefan; Chęcińska, Liliana; Lork, Enno; Sanz Camacho, Paula; Ashbrook, Sharon Elizabeth Marie; Athukorala Arachchige, Kasun Sankalpa; Cordes, David Bradford; Slawin, Alexandra Martha Zoya; Beckmann, Jens; Woollins, J Derek (2015-03-02) - Journal article
      A series of peri-substituted phosphorus-tellurium systems R’Te–Acenap–PR2 (R’ = Ph, p-An, Nap, Mes, Tip; R = iPr, Ph) exhibiting large “through space” spin-spin coupling constants and the “onset” of three-centre four-electron ...
    • Polymorphism, weak interactions and phase transitions in chalcogen-phosphorus heterocycles 

      Sanz Camacho, Paula; Stanford, Martin; McKay, David; Dawson, Daniel McLean; Athukorala Arachchige, Kasun Sankalpa; Cordes, David Bradford; Slawin, Alexandra Martha Zoya; Woollins, John Derek; Ashbrook, Sharon Elizabeth Marie (2018-06-28) - Journal article
      A series of novel P-E containing heterocycles with aromatic backbones were synthesised and characterized by single crystal and powder X-ray diffraction, microanalysis and mass spectrometry. 31P and 77Se solution- and ...
    • Synthetic, spectroscopic and structural studies of chalcogen peri-substituted heterocycles : a solid-state NMR perspective 

      Sanz Camacho, Paula (University of St Andrews, 2016-06-27) - Thesis
      Chalcogen-containing materials are an area of increasing interest for spintronic applications. The synthesis, structures and reactivity of these novel compounds are normally studied by solution-state nuclear magnetic resonance ...
    • Unusual intermolecular “through-space” J couplings in P–Se heterocycles 

      Sanz Camacho, Paula; Athukorala Arachchige, Kasun Sankalpa; Slawin, Alexandra Martha Zoya; Green, Timothy F.G.; Yates, Jonathan R.; Dawson, Daniel McLean; Woollins, J Derek; Ashbrook, Sharon Elizabeth Marie (2015-05-20) - Journal article
      Solid-state NMR spectra of new P–Se heterocycles based on peri-substituted naphthalene motifs show the presence of unusual J couplings between Se and P. These couplings are between atoms in adjacent molecules and occur ...
