  1. 1. Iodotrimethylsilane-Promoted Conjugate Addition of Organocopper Reagents, DDQ oxidation of Arylpropenes and Synthesis of 2-Arylcoumarans

    University dissertation from Chalmers University of Technology

    Author : Tommy Iliefski; Chalmers tekniska högskola.; Chalmers University of Technology.; [1998]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Kemi; Chemistry; conjugate addition; 1; 4-addition; iodotrimethylsilane; TMSI; organocopper; copper acetylides; 2; 3-dichloro-5; 6-dicyanobenzoquinone; DDQ; cinnamaldehyde; arylpropene; neolignan; arylcoumaran;

    Abstract : This thesis is divided into three parts: conjugate additions of organocopper reagents, DDQ oxidations of arylpropenes, and synthesis and steric assignment of 2-arylcoumarans. The iodotrimethylsilane(TMSI)-promoted conjugate addition of alkylcopper and copper acetylides to certain a,b-unsaturated carbonyl compounds is investigated. READ MORE

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

    University dissertation from Chalmers University of Technology

    Author : Karolina Nilsson; Chalmers tekniska högskola.; Chalmers University of Technology.; [1997]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Kemi; Chemistry; mechanism; conjugate addition; organocopper reagents; ynoates; ynones; enoates; pi-complexes; lithium dimethylcuprate; cyanocuprate; 13C and 15N NMR spectroscopy; 6Li; 1H-HOESY;

    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
