  2. 1. Mechanistic Studies of Organocopper Chemistry by NMR Spectroscopy: Conjugate Additions to Alkynes and Alkenes

    Author : Karolina Nilsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cyanocuprate; organocopper reagents; ynones; lithium dimethylcuprate; 13C and 15N NMR spectroscopy; pi-complexes; mechanism; enoates; 6Li; 1H-HOESY; ynoates; conjugate addition;

    Abstract : This thesis focuses on the mechanisms of organocopper reactions, in particular the reactions with activated alkynes (ynoates and ynones). These reactions are of interest in the formation of new highly functionalized double bonds with control of the stereochemistry. READ MORE

  4. 2. Chiral Lithium N,P-amide Complexes. Synthesis, Applications and Structural Studies by NMR and DFT

    Author : Petra Rönnholm; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; 6Li NMR; Asymmetric synthesis; N; P-ligands; DFT; Molecular mechanics;

    Abstract : Enantiospecific synthesis reactions are of intense interest, owing to the increasing request for enantiopure compounds in both research and industry. Lithium amides containing a secondary chelating group are a class of powerful ligands for asymmetric addition reactions. READ MORE
