General Description

2,8-Dimethyldibenzothiophene is a chemical compound with the molecular formula C14H12S. It is a type of dibenzothiophene, which is a class of organic compounds containing a central thiophene ring. This chemical is commonly found in petroleum and its derivatives, and it is known to contribute to the formation of soot and other pollutants during combustion. 2,8-Dimethyldibenzothiophene is also of interest in the field of organic electronics, as it can be used in the production of organic light-emitting diodes (OLEDs) and organic photovoltaic devices. Additionally, it has been studied for its potential use as a fluorescence probe and in the development of new materials for various applications.

Check Digit Verification of cas no

The CAS Registry Mumber 1207-15-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,2,0 and 7 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1207-15:
(6*1)+(5*2)+(4*0)+(3*7)+(2*1)+(1*5)=44
44 % 10 = 4
So 1207-15-4 is a valid CAS Registry Number.

A Pd-catalyzed optional approach for the synthesis of dibenzothiophenes

Song, Juan,Wu, Hao,Sun, Wei,Wang, Songjiang,Sun, Haisen,Xiao, Kang,Qian, Yan,Liu, Chao

, p. 2083 - 2087 (2018)

A direct and practical approach for the construction of DBTs was developed via a Pd-catalyzed tandem reaction, in which commercially available o-bromo-iodobenzenes combined with benzene thiols or iodobenzenes combined with o-bromo-benzene thiols were applied. These two approaches will provide an alternative for the synthesis of DBT derivatives.

Hydrodesulfurization of Alkyldibenzothiophenes over a NiMo/Al2O3 Catalyst: Kinetics and Mechanism

Meille, Valerie,Schulz, Emmanuelle,Lemaire, Marc,Vrinat, Michel

, p. 29 - 36 (1997)

The transformation mechanism of dibenzothiophene, 4-methyldibenzothiophene, 4,6-dimethyldibenzothiophene, and 2,8-dimethyldibenzothiophene has been studied in a batch reactor over an industrial NiMo/Al2O3 hydrotreating catalyst at 573 K under 5 MPa of hydrogen pressure. A detailed mechanistic study including competitive catalytic experiments proved that the adsorption of the most refractory molecules at the catalyst surface was not the rate-determining step for their transformation. Our results imply that the hydrodesulfurization of these compounds occurs on one single type of sites by a flat adsorption, leading to a preliminary partial hydrogenation of one aromatic ring. Variations in reactivities of the dibenzothiophene derivatives were thus explained by different reaction rates for the C-S bond scission due to steric hindrance generated by the methyl substitution near the sulfur atom.

Palladium catalysis based one-pot synthesis method for DBTs (dibenzothiophenes)

-

Paragraph 0025-0030, (2020/05/12)

The invention discloses a palladium catalysis based one-pot synthesis method for DBTs (dibenzothiophenes). An inorganic base is added to an N,N-dimethylacetamide solution, with a palladium catalyst/ligand as a catalysis system, o-bromoiodobenzene derivatives or iodobenzene derivatives and thiophenol derivatives taken as raw materials are subjected to a reaction in nitrogen atmosphere, and DBTs areobtained through separation. The simple, economical and easily available raw materials are taken as substrates, all-position-substituted DBTs are synthesized on the basis of palladium catalyzed cascade reaction, and DBTs have great application prospect in medical synthesis intermediates and organic optoelectronic material science.
