Synthèse et ouverture d’ions phosphiraniums

Abstract : Phosphiraniums ions are known for more than fifty years. However, heir C-centered ring opening has never been reported. This novel reactivity would grant access to β-functionalized phosphines in an innovative manner, opening the way to new synthetic perspectives. Novel phosphiranes as well as their corresponding phosphiraniums have been synthesized through alkylation and arylation reactions. Then, these compounds were reacted with different nitrogen compounds allowing their ring opening in a C-centered fashion for the very first time. New β-aminophosphines could be accessed this way in regards for their innovative structure and synthetic pathway. Various parameters have been studied to increase our understanding on these specific yet promising reactions.In this line, along this PhD project, interactions and factors which might rule this particular reactivity were screemed.
