Diaryliodonium salts offer potential as novel reagents for arylation chemistry. An overall goal and successful outcome of this work has been to further understanding of diaryliodonium salt chemistry by developing practical methods that enable chemists more convenient access to these reagents, for the purpose of reaction development. To this end a robust and convenient preparation method has been developed and resulted in novel commercially available diaryliodonium salts. The remainder of the work described, has focused on understanding the parameters important to diaryliodonium mediated arylation and has resulted in a solid framework that multiple future development efforts can build upon.
A strategy adopted throughout this work was to use multivariate methodologies such as Design of Experiments (DoE). Applicable chapters show the results of optimization studies that were carried out using DoE, during the course of this work. Additionally, the desire to further realize the potential that DoE has to offer inspired of a search for parameters to study fundamental reactivity. Chapter 2 details the development of a practical diaryliodonium salt synthesis that is convenient, facile, and economical. A detailed procedure is also included and was drafted to the requirements for publication in the journal Organic Synthesis. Finally, limitations and future directions of the method are discussed. Chapter 3 describes studies aimed at understanding the role of the counter anion; a very practical counter anion screening method is presented. Future directions are discussed and include detailed characterization of diaryliodonium salts by NMR. Chapter 3 also describes a practical, scalable, and rapid salt exchange method developed during this work. Chapter 4 describes the results obtained in studying an azidation reaction via solubility parameters. All Supporting Information, including characterization data and experimental details, are provided in Chapter 5.
