1. Diaryliodonium Salts : Development of Synthetic Methodologies and α-Arylation of Enolates
Sammanfattning : 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. LÄS MER
2. Efficient and High-Yielding Routes to Diaryliodonium Salts
Sammanfattning : 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. LÄS MER
3. Carbon Nanostructures – from Molecules to Functionalised Materials : Fullerene-Ferrocene Oligomers, Graphene Modification and Deposition
Sammanfattning : 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.
