Pittalis, Mario and Azzena, Ugo Gavino and Carraro, Massimo and Pisano, Luisa (2013) Active-alkali metal promoted reductive desulfurization of dibenzothiophene and its hindered analogues. In: 35. Convegno della Divisione di chimica organica della Società Chimica Italiana, 9-13 settembre 2013, Sassari, Italia. [S.l.], Società Chimica Italiana, Divisione di chimica organica. P69. Conference or Workshop Item.
Reductive desulfurisation of organic compounds is of importance both in organic synthesis and in industry. Benzo- and dibenzothiophenes are between the most abundant sulphur containing impurities in crude oils, and their desulfurization is a mandatory issue in the production of non polluting fuels. Following our interest in the development of efficient alkali metal-mediated synthetic procedures and alternative protocols for the chemical transformation of widespread environmental contaminants we wish to report here on the effectiveness of sodium and lithium metals, in the presence of catalytic amounts of tetraphenylethylene (TPE), in promoting the reductive desulfurization of dibenzothiophene, as well as of the corresponding sulfone and sulfoxide.
