TL;DR: The influence of anthracene, phenanthrene, fluorene, acridine and carbazole on the transformation of 4,6-dimethyldibenzothiophene on a NiMo/Al2O3 catalyst was studied in this article.
Abstract: The influence of anthracene, phenanthrene, fluorene, acridine and carbazole on the transformation of 4,6-dimethyldibenzothiophene on a NiMo/Al2O3 catalyst was studied. Reactivities have been evaluated under increasing concentrations of inhibitors and negative effect of some polycondensed ring aromatic compounds has been shown to be in the same order of magnitude than that of N-containing compounds. Moreover, such inhibition was proposed to be due to some partially hydrogenated molecule and conclusions relative to the practice of deep hydrodesulfurization (HDS) were drawn.

TL;DR: In this article, asymmetric sulfur-containing ligands based on a dibenzothiophene backbone have been prepared and tested in asymmetric palladium-catalyzed allylic substitutions leading to up to 77% e.g.

TL;DR: A selective removal of nitrogen compounds from gasoils is proposed, using a recyclable sorbent capable of forming charge-transfer complexes; the selective elimination of nitrogen compound strongly improves the hydrodesulfurization of denitrogenated feed.

Abstract: New asymmetric sulfur-containing ligands based on a dibenzothiophene backbone have been prepared. The chirality was introduced by two oxazoline moieties placed near the sulfur atom. These C 2 -symmetric bis(oxazolines) have been successfully tested in asymmetric palladium-catalyzed allylic substitutions leading to up to 77% e.e.
