  1. 1. C–H and Si–H functionalization using redox-active diazo compounds and decarboxylative coupling

    Författare :Rajdip Chowdhury; Abraham Mendoza; Darren Dixon; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; carbenes; radicals; redox-active esters; indoles; carboxylic acids; silanes; photochemistry; Organic Chemistry; organisk kemi;

    Sammanfattning : The work presented in this thesis is based on two basic organic chemistry concepts: carbene catalysis and radical coupling reactions. Diazo compounds in the presence of transition-metal catalysts are known to be excellent reagents for the construction of C–X bonds (X = C, Si, N, O, etc.) under mild conditions. LÄS MER

  3. 2. Asymmetric Synthesis using Redox-Active Diazocompounds as Chiral Carbon Atom Precursors

    Författare :Matteo Costantini; Abraham Mendoza; Armido Studer; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; redox-active carbenes; mechanistic investigation; cyclopropanes; asymmetric catalysis; photochemistry; organisk kemi; Organic Chemistry;

    Sammanfattning : This thesis summarizes the development of general and efficient methods to synthesize enantiomerically enriched cyclopropane compounds. The works reported herein exploit the opportunity presented by redox-active esters to explore the orthogonality between asymmetric carbene-transfer and geminal radical generation. LÄS MER
