One-pot cascade synthesis of dibenzothiophene-based heterobiaryls from dibenzothiophene-5-oxide

open access: yesOrganic & Biomolecular Chemistry, 2023
A one-pot protocol to access 4-substituted dibenzothiophene (DBT) from dibenzothiophene-5-oxide (DBTO) was developed via a sulfoxide directed C–H metalation/B2Pin2 mediated reduction/Suzuki coupling cascade process.

Activity Evaluation of CoMo Nanoparticles Supported on Meso-microporous Composites in Dibenzothiophene Hydrodesulphurization

open access: yesBulletin of Chemical Reaction Engineering & Catalysis, 2020
CoMo-supported mesoporous catalysts were synthesized by 50 wt% of HZSM-5 and 50 wt% of FSM-16, KIT-6, and MCM-48. These catalysts were prepared by the wet-impregnation method and pre-sulfided with CS2.

Adsorption of thiophene, dibenzothiophene, and 4,6-dimethyl dibenzothiophene on activated carbons [PDF]

open access: yesAdsorption Science & Technology, 2016
Four activated carbons (ACs) activated by different activation methods from different precursors were heat-treated at 600℃ to decrease surface oxygen functional groups and to separate the effect of pore texture from surface chemistry on their sulfur adsorption performance.
