1. Development and Applications of Hypervalent Iodine Compounds : Powerful Arylation and Oxidation Reagents
Abstract : The first part of this thesis describes the efficient synthesis of several hypervalent iodine(III) compounds. Electron-rich diaryliodonium salts have been synthesized in a one-pot procedure, employing mCPBA as the oxidant. Both symmetric and unsymmetric diaryliodonium tosylates can be isolated in high yields. READ MORE

2. Synthetic and Mechanistic Studies with Iodine(III) Reagents
Abstract : This thesis describes the development of metal-free transformations and mechanistic studies on the reactivity of two classes of hypervalent iodine reagents: diaryliodonium salts and vinylbenziodoxolones (VBX). Recently, they have been recognized as valuable synthetic reagents with broad applicability in organic synthesis. READ MORE
