Chloro-arylation of Alkenes via Cooperative Photoredox and Atom-transfer Catalysis
… diversity from readily available alkenes and diaryliodonium salts. The developed transformation benefits from a high degree of modularity through the independent functionalization of diaryliodonium salts and alkenes. In addition, broad functional group tolerance is observed under the mild …

Applications of Hypervalent Iodine Reagents: From Enantioselective Copper-Catalysed Arylation-Semipinacol Cascade to Methionine Functionalisation for Peptide Macrocyclisation
… exploitation of the reactivity of aryliodonium salts as electrophile transfer reagents. In the first part of the thesis, diaryliodonium salts are employed as arylation reagents for the enantioselective copper-catalysed arylative semipinacol rearrangement (SPR) of various tertiary allylic …

Towards the Development, Application and Understanding of Copper-Catalysed Alkene Functionalisation Processes Using Iodonium Salts
… the combination of catalytic copper and iodonium salts towards the functionalisation of alkenes. Chapter 2 details the development of an enantioselective and regiodivergent allylic amide arylation procedure using a specific copper(II)-bisoxazoline pre-catalyst and hexafluorophosphate …

Hypervalent iodine reagents for protein functionalisation
… derivatives using hypervalent iodonium salts, producing versatile conjugates that can undergo further bioorthogonal modifications. This powerful strategy proceeds with high efficiency and chemoselectivity across a range of small proteins and polypeptides. In this work, we describe the …
