Now you put water in a cup, it becomes the cup; You put water into a bottle it becomes the bottle; You put it in a teapot it becomes the teapot. Now water can flow or it can crash. Be water, my friend. Bruce Lee, 2000 Acknowledgment Desde pequeno, sempre quis viajar e conhecer os lugares mencionados nos livros que lia. A oportunidade de fazer um doutorado na França me permitiu conciliar um sonho de infância com meu desenvolvimento acadêmico. Hoje, me sinto realizado tanto pessoalmente quanto profissionalmente. Muitas pessoas foram imprescindíveis para concluir essa etapa de minha vida com sucesso. Antes de mais nada, gostaria de agradecer a minha família, que sempre me apoiou, nunca desacreditando do meu potencial, em especial minha mãe Selma, meu irmão do coração Eduardo e minhas tias Celi e Stella. Me gustaría también agradecer a mi novia Patricia, por su cariño, amor y paciencia, incluso los momentos de mucho estrés en el fin de la tesis. Gracias mi amor. I’d also like to thank my friends, made during the first period in Toulouse, specially Marion and Roberto, for the several hours talking about science and/or nothing, around some coffee and/or beer. Je souhaite aussi remercier mes amis de la deuxième époque que si passait à Rennes, surtout Lucas, Anabella, Eleonora, Cyril, Rachid, Camila et tous les autres membres du bâtiment 10 C, sans lesquelles le séjour dans la Bretagne serait impossible. Um grande abraço para minha família gaúcha, Lili, Betão e Pepê, que me acolheu pela terceira vez com a casa e o coração abertos, transformando uma simples época de trabalho em um período de felicidade e aprendizado. Un grand merci à Gilles, qui m’a accepté comment thésard et m’a guidé par les moments les plus ténèbres comme un ange et par les moments des faiblesses avec force, ce que m’a permis de passer au-delà de mes limites. Um grande obrigado a Katia, que também me acompanha desde o mestrado de maneira tão carinhosa que as vezes a vejo como tia ao invés de professora. Thanks to the O group and the other members of the LCC in Toulouse, with whom we shared good moments and helped me so much to adapt to the new country. Thank you also members of the OMC group in Rennes, very important to me in the final period of this journey. Je souhaite remercier tous les membres du jury qui ont accepté de participer à ma soutenance de thèse et de juger mon travail. Merci à Umit Demirci et à Ghenwa Bouhadir pour fournir une excellente discussion et proportionner une vue plus approfondie de mon sujet de thèse. Merci à Loic Le Pluart et Sophie Guillaume pour enrichir la discussion avec votre expertise. Je remercie encore à Gilles Alcaraz, sans toi, je serai encore en train de rédiger.

  • Synthetic Studies of Sodium Aminodiboranate Salts with Electron- Withdrawing Substituents
    SYNTHETIC STUDIES OF SODIUM AMINODIBORANATE SALTS WITH ELECTRON- WITHDRAWING SUBSTITUENTS BY CONNOR I. DALY THESIS Submitted in partial fulfillment of the requirements for the degree of Master of Science in Chemistry in the Graduate College of the University of Illinois at Urbana-Champaign, 2020 Urbana, Illinois Adviser: Professor Gregory S. Girolami ABSTRACT Magnesium diboride, MgB2, has the highest superconducting critical temperature of all traditional superconductors and is being considered for the fabrication of superconducting integrated circuits that can operate at higher temperatures than analogous niobium alloy circuits. A significant barrier to preparing superconducting MgB2 thin films, however, is that the films must be deposited below 300 °C to prevent Mg from subliming out of the film and causing loss of the superconducting properties. One approach to solve this problem is to prepare low- temperature chemical vapor deposition (CVD) precursors which would enable deposition of MgB2 at temperatures low enough to prevent loss of Mg from the thin film. In chapter 1, we describe the synthesis of three new sodium aminodiboranate salts, Na(BH3)2NRR′, with trimethylsilyl groups on nitrogen. These compounds – sodium N,N-bis- (trimethylsilyl)aminodiboranate, sodium N-trimethylsilylaminodiboranate, and sodium N- methyl-N-trimethylsilylaminodiboranate – were prepared by the reaction of μ-aminodiborane(6) species with sodium hydride. IR, 1H NMR, 13C NMR, and 11B NMR spectra are reported for all of these compounds, along with the crystal structures of N-trimethylsilylaminodiboranate and N- methyl-N-trimethylsilylaminodiboranate. Comparisons of 11B NMR chemical shifts suggest that steric, inductive, and hyperconjugative effects of the substituents on nitrogen are all in competition in these systems.

    Hydroboration Studies of Olefins with Heterocyclic Hydroborating Reagents with Various Transition Metal Complexes: Attemped Diastereoselective Synthesis of Homoallylic Alcohols via Hydroboration. Thesis submitted in fulfilment of the requirements for the degree Master of Science By Mbongeni M. Shungube School of Chemistry and Physics College of Agriculture, Engineering and Science University of KwaZulu-Natal Pietermaritzburg December 2016 Declaration The experimental work described in this dissertation was carried out in the School of Chemistry, College of Agriculture, Engineering and Science, University of KwaZulu-Natal, Pietermaritzburg, under the supervision of Professor Ross S. Robinson. I hereby declare that these studies represent original work by the author and have not otherwise been submitted in any form for any degree or diploma to any tertiary institution. Where the use of published information from other authors has been made and it is duly acknowledged in the text. Signed …………………………………………… Mbongeni M. Shungube (Candidate) I hereby certify that this statement is correct. Signed …………………………………. Professor Ross S. Robinson (Supervisor) i Abstract Hydroboration is one of the key routes to afford organoborane esters which are versatile intermediate in organic synthesis. Investigations of different hydroborating reagents and catalysts toward hydroboration present alternative to achieve organoborane ester with different stability, selectivity, and yield. Hence, a part of this study was focused on the preparation of heterocyclic hydroborating reagents with a single site available for hydroboration. Four reagents were prepared which included the well-known catecholborane (23) and pinacolborane (24) and the hardly studied 2,3-dihydro-1,3,2-benzodiazaborole (31) and 2,3-dihydro-1,3,2-benzoxazaborole (34). A study to utilize hydroboration to prepare allylic boronic esters using the four hydroborating reagent above was also undertaken.
