    • Gold Complex Preparation, Catalysis and Catalyst Activation 

      Jónsson, Helgi Freyr (Doctoral theses at NTNU;2022:195, Doctoral thesis, 2022)
      Gold complexes and salts have proven to be exceptional catalysts for the activation of carbon-carbon multiple bonds towards nucleophilic attack. Gold catalysts allow for the synthesis of complex products under mild conditions. ...

    • Studies on Gold-Nitrone Chemistry 

      Jónsson, Helgi Freyr (Master thesis, 2017)
      The gold(I)-nitrone catalysed cyclotrimerization of diaryl propargyl acetals was studied. Gold(I)-nitrone and gold(I)/gold(III)-oxadiazole complexes were also synthesised.

    • Syntheses and Catalytic Studies of Axially Chiral Gold N-Heterocyclic Carbene Complexes 

      Øvrebø, Benedicte (Master thesis, 2021)
      Målet med dette masterprosjektet var å syntetisere aksialt kirale NHC-preligander med et benzimidazol-naftyl rammeverk, og koordinere disse til gull(I) og gull(III), etterfulgt av katalytisk testing av gullkompleksene. ...
