Expeditious and scalable synthesis of 1,2,3,4-tetrahydro-4,6-dimethyldibenzothiophene for ultra-deep hydrodesulfurization study
Abstract
To fully understand the catalytic hydrodesulfurization of the most refractory sulfur-containing compound 4,6-dimethyldibenzothiophene (DMDBT) is important for the progress of ultra-deep hydrodesulfurization (HDS) technology. 1,2,3,4-tetrahydro-4,6-dimethyldibenzothiophene (4H-DMDBT) plays a critical role in the kinetic study of DMDBT hydrodesulfurization. Through existing methods, it is very difficult to obtain sufficient 4H-DMDBT for mechanism study. In this work, we have developed an expeditious and scalable synthetic route featuring cheap starting materials, safe and green reagents and procedures that is suitable for an organic synthetic laboratory.
