2786-08-5

Dibenzothiophene-4-carboxylic acid (DBT) is a heterocyclic organic compound with the molecular formula C12H9NO2S2. It is a derivative of dibenzothiophene, which is a sulfur-containing analog of naphthalene. DBT is a white crystalline solid that is insoluble in water but soluble in organic solvents. It is an important chemical intermediate in the synthesis of various pharmaceuticals, agrochemicals, and dyes. DBT is also a significant component in the sulfur-containing compounds found in crude oil, which can cause problems in petroleum refining processes. Its presence in crude oil can lead to the formation of coke and other deposits in refining equipment, which can reduce the efficiency and lifespan of the equipment. Therefore, the removal or conversion of DBT and other sulfur-containing compounds is an important aspect of petroleum processing.

2786-08-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2786-08-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,7,8 and 6 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 2786-08:
(6*2)+(5*7)+(4*8)+(3*6)+(2*0)+(1*8)=105
105 % 10 = 5
So 2786-08-5 is a valid CAS Registry Number.

Palladium-catalyzed oxidative coupling of arylboronic acid with isocyanide to form aromatic carboxylic acids

Chen, Zhen-Bang,Liu, Kui,Zhang, Fang-Ling,Yuan, Qing,Zhu, Yong-Ming

, p. 8078 - 8083 (2017/10/10)

A valuable palladium-catalyzed oxidative coupling of aryl- and alkenyl borides with isocyanide for the synthesis of corresponding carboxylic acids has been developed. With wide substrate scopes and good functional group tolerance, this reaction offers corresponding carboxylic acids in moderate to excellent yields.
