Vers l'introduction douce de groupes fluorés émergents oxygénés et soufrés

Abstract : The manuscript deals the development of new fluorinating reagents and their reactivity in various reactions.In the first part, we were interested in developing new fluoride sources from ionic liquids with imidazolium as the cationic part, and associated to the fluoride as anion. Two ionic liquids, [bmim][F] and [bdmim][F], were obtained. They were then tested in monofluoration and fluorodesulfurization reactions.The second chapter concerns the development of new trifluoromethoxylation reagents.We began by synthetizing new carbene precursors with an OCF3 group. We then evaluated their reactivities in different processes. A second part was centered on a FAR compound and its reactivity in aromatic acylation reactions.Finally, the last chapter describes the behavior of SF6 in electrochemistry reduction with different conditions, the aim being to have a new source of SF5 radical. After a first part concerning analytical studies of the sulfur hexafluoride, the aforementioned compound was engaged an electrosynthetic process to trap intermediate species coming from its reduction.
