  1. 1. Novel Pincer Complex-Catalyzed Transformations Including Asymmetric Catalysis

    University dissertation from Stockholm : Institutionen för organisk kemi

    Author : Juhanes Aydin; Stockholms universitet.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; pincer; palladium; catalysis; chiral; asymmetric; palladium IV; allylation; aldol; aminoacid; C-H functionalization; cross-coupling; homoallylic; heck reaction; tridentate ligand; NATURAL SCIENCES Chemistry; NATURVETENSKAP Kemi; Organic Chemistry; organisk kemi;

    Abstract : This thesis is focused on the development of new pincer complex-catalyzed transformations. Optimization of the catalytic properties (fine-tuning) was directed to increase the catalytic activity as well as the chemo-, stereo- and enantioselectivity of the complexes. READ MORE

  3. 3. Development of New Synthetic Routes to Organoboronates by Catalytic Allylic Substitution and C-H bond Functionalization

    University dissertation from Stockholm : Department of Organic Chemistry, Stockholm University

    Author : Vilhelm Olsson; Stockholms universitet.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Palladium; Iridium; Boron; Catalysis; NATURAL SCIENCES Chemistry Organic chemistry; NATURVETENSKAP Kemi Organisk kemi; organisk kemi; Organic Chemistry;

    Abstract : This thesis describes the development of new catalytic methods for the synthesis and application of organometallic reagents, mainly focusing on allylboronic acid derivatives. Thus, palladium pincer-complex catalysis has been applied for extending the scope of palladiumcatalyzed borylation reactions in the synthesis of regio- and stereodefined functionalized allylboronic acid derivatives.

  4. 4. Catalysis in Dynamic Systems: Control within Molecular Reaction Networks

    University dissertation from Stockholm : Kungliga Tekniska högskolan

    Author : Fredrik Schaufelberger; KTH.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; systems chemistry; dynamic covalent chemistry; catalyst screening; reaction networks; organocatalysis; imine exchange; combinatorial chemistry; dynamic systemic resolution; feedback; error-correction; Morita-Baylis-Hillman reaction; C-H activation; H-bond catalysis; transamination; Kemi; Chemistry;

    Abstract : Life as we know it is based on complex networks of biochemical reactions that constantly interact within large dynamic systems. The field of systems chemistry uses chemical models to study how reaction networks – and thereby life – function on a molecular level. READ MORE
