Synthesis, Structure and Reactivity of Phosphorus and Arsenic Heterocycles
Synthesis, Structure and Reactivity of Phosphorus and Arsenic Heterocycles Darren Michael Charles Ould A thesis submitted to Cardiff University in candidature for the degree of Doctor of Philosophy March 2020 I. Acknowledgements To begin with, I would like to extend my thanks and gratitude to my supervisor Dr Rebecca Melen for firstly giving me the opportunity to undertake my PhD in her group and secondly for allowing me to present at a number of conferences both domestically and internationally. Travelling to Canada in the summers of both 2018 and 2019 as part of an exchange program and to present at the Canadian Chemistry Conference and Exhibition 2019 will undoubtedly go down as highlights of my PhD. Thanks must be given to the Melen group both past and present. In particular though to Dr Adam Ruddy, Dr Yashar Soltani and Jamie Carden for their help and suggestions, as well as providing a great working atmosphere. My further thanks to Dr Lewis Wilkins for his help and suggestions, but moreover for teaching me the basics of single crystal X-ray crystallography as well as solving a number of my early structures (compounds 6a, 7, 15a–c, 16a–c, 17 and 18). I am grateful for the hard work to the students I have supervised during the course of my PhD, Matthew de Vere-Tucker, Kayla Trafford, Emily Tansley, Dorothea Engl and especially Alex Rigby who helped me develop the initial diazaphosphole and diazarsole work, as well as helping me crystallise a number of complexes (6a, 7, 15a–c, 16a–c and 17).
