일반 설명

Dibenzothiophene is an important polycyclic aromatic hydrocarbon (PAH). Kinetics of hydrodesulfurization of dibenzothiophene on presulflded molybdenaalumina catalyst has been studied in a high-pressure-flow microreactor. Biodesulfurization of dibenzothiophene by selective cleavage of carbon sulphur bonds by a thermophilic bacterium Bacillus subtilis WU-S2B has been reported.

애플리케이션

Dibenzothiophene was employed as heavy model sulfur compound to investigate the effect of heavy sulfur compounds on the percentage of sulfur in gasoline range during the Fluid Catalytic Cracking (FCC) process.

With the IPr ligand (IPr=1,3-bis-(2,6-diisopropylphenyl)imidazol-2-ylidene) on gold(I) excellent yields in the benzanellation of 2-substituted thiophenes, benzothiophenes, pyrroles, benzofurans, and indoles were achieved. The 1-siloxybut-3-ynyl side chains, incorporated in the anellation, are easily accessible by the addition of a propargyl metal
