  1. 1. Diaryliodonium Salts : Development of Synthetic Methodologies and α-Arylation of Enolates

    Author : Marcin Bielawski; Berit Olofsson; Antonio Togni; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Hypervalent Iodine Compounds; One-Pot Synthesis; Regiospecific Synthesis; Aromatic Substitution; Aryl Iodides; Arenes; Boronic Acids; Heteroaromatics; Arylations; Reaction Mechanisms; Density Functional Calculations; Large Scale Synthesis; Organic synthesis; Organisk syntes; organisk kemi; Organic Chemistry;

    Abstract : This thesis describes novel reaction protocols for the synthesis of diaryliodonium salts and also provides an insight to the mechanism of α-arylation of carbonyl compounds with diaryliodonium salts.  The first chapter gives a general introduction to the field of hypervalent iodine chemistry, mainly focusing on recent developments and applications of diaryliodonium salts.

  2. 2. Efficient and High-Yielding Routes to Diaryliodonium Salts

    Author : Marcin Bielawski; Berit Olofsson; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Hypervalent Iodine Compounds; One-Pot Synthesis; Regiospecific Synthesis; Aromatic Substitution; Aryl Iodides; Arenes; Boronic Acids; Organic chemistry; Organisk kemi;

    Abstract : This thesis summarizes three novel and general reaction protocols for the synthesis of diaryliodonium salts. All protocols utilize mCPBA as oxidant and the acids used are either TfOH, to obtain triflate salts, or BF3•Et2O that gives the corresponding tetrafluoroborate salts in situ. READ MORE

  3. 3. Carbon Nanostructures – from Molecules to Functionalised Materials : Fullerene-Ferrocene Oligomers, Graphene Modification and Deposition

    Author : Michael Nordlund; Helena Grennberg; Mogens Brøndsted Nielsen; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Fullerenes; Graphene; Deposition; Functionalization; Organometallic complexes; Chemistry with specialization in Organic Chemistry; Kemi med inriktning mot organisk kemi;

    Abstract : The work described in this thesis concerns development, synthesis and characterisation of new molecular compounds and materials based on the carbon allotropes fullerene (C60) and graphene.A stepwise strategy to a symmetric ferrocene-linked dumbbell of fulleropyrrolidines was developed.
