  1. 1. Catalytic Functionalization of Allylic Substrates by Palladium Pincer Complexes

    Författare :Nicklas Selander; Kálmán Szabó; David Milstein; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Catalysis; Palladium; Pincer Complex; Boron; Multicomponent Reaction; Organic chemistry; Organisk kemi; organisk kemi; Organic Chemistry;

    Sammanfattning : This thesis is based on the development of novel catalytic reactions for the synthesis and application of organometallic reagents. The main focus is directed towards organoboronate derivatives. We developed an efficient procedure for converting allylic alcohols to the corresponding allylboronates using palladium pincer complexes as catalysts. LÄS MER

  3. 2. Development of Multi-Component Reactions using Catalytically Generated Allyl Metal Reagents

    Författare :Nicklas Selander; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic Chemistry; Organic chemistry; Organisk kemi;

    Sammanfattning : This licentiate thesis is based on the development of catalytic reactions for the synthesis and application of organometallic reagents. By use of palladium pincer-complex catalysts, we have developed an efficient procedure for the synthesis of allylboronates starting from allylic alcohols. LÄS MER

  4. 3. Sustainable methods for the preparation of diverse Au(I) complexes

    Författare :Fredric Ingner; Lukasz Pilarski; Nicklas Selander; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry with specialization in Organic Chemistry; Kemi med inriktning mot organisk kemi;

    Sammanfattning : Over the last three decades, the role of Au(I) complexes has become increasingly important within medicinal chemistry, material applications and synthesis. Alas, their preparation remains reliant on harsh reaction conditions, hazardous solvents, exogenous additives and, often, high reaction temperatures. LÄS MER

  5. 4. Development of new Catalytic Methods for the Selective Synthesis of Heterocycles

    Författare :Stalin Reddy Pathi Pati; Nicklas Selander; Masaharu Nakamura; Stockholms universitet; []
