Resumen
Ring opening reactions of strained heterocycles (epoxides, aziridines, thiiranes) by silyl chalcogenides, such as thiosilanes and selenosilanes, can be efficiently performed in a variety of ionic liquids, which can behave as reaction media and in some cases also as catalysts. This protocol enables an alternative access to β-functionalized sulfides and selenides under mild conditions.

Resumen
The reactivity of N-thiophthalimides with silyl chalcogenides is described. Treatment of N-thiophthalimides with bis(trimethylsilyl) sulfide [(Me3Si)2S] leads to the formation of a mixture of the corresponding disulfides and trisulfides. On the other hand, N-thiophthalimides react with bis(trimethylsilyl) selenide [(Me3Si)2Se] under TBAF catalysis to smoothly give variously substituted diaryl, divinyl, and dialkyl disulfides; formation of a selenotrisulfide (dithiaselane, RSSeSR) is rationalized as an intermediate. Exploiting the different chemical behavior of silyl chalcogenides, we have disclosed a novel, selective, and operationally simple method to access disulfides in good yields under mild conditions.

Resumen
In the course of this PhD thesis the research was mainly focused on the study of the reactivity of sulfurated and selenated derivatives with different substrates, aimed to develop mild and general approaches to obtain useful acyclic and cyclic compounds containing sulfur and/or selenium moieties, together with other heteroatoms (N, O). In this context, synthetic strategies based on the functionalization of bidentate compounds and on the reactivity of various silanes were studies. Particular attention was also paied to the determination of the antioxidant activity of selected, novel and simple molecules obtained during this work, as well as in the evaluation of their behaviour as synthetic mimics of glutathione peroxidase (GPx). In this connection was also studied the functionalization of natural substrates, such as eugenol, limonene, resveratrol and ascorbic acid, to introduce these chalchogens at selected positions of the natural molecular skeleton, in order to evaluate whether a synergistic effect could be obtained to increase their activity. During the period spent at the University of Bristol the research was focused on the chemistry of boronic esters as versatile intermediates in the asymmetric synthesis of a variety of organic compounds, with the aim to apply these findings also to the stereoselective synthesis of suitable enantioenriched precursors of more complex sulfurated and selenated derivatives.
