1211-32-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1211-32-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,2,1 and 1 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1211-32:
(6*1)+(5*2)+(4*1)+(3*1)+(2*3)+(1*2)=31
31 % 10 = 1
So 1211-32-1 is a valid CAS Registry Number.

Copper and iron-assisted palladium-catalyzed direct arylation of azoles with arylboronic acids under ligand and base-free conditions

Wu, Xiang-Mei,Shen, Qiu-Xian

, p. 668 - 673 (2013)

The direct arylation of azoles with arylboronic acids is effectively promoted by PdCl2 in the presence of copper and iron salts under ligand and base-free conditions. This reaction can be applied to heterocycles such as benzothiazole, benzoxazole, 1-methylbenzimidazole and 4,5-dimethylthiazole with moderate to good yields.

Method for catalytically synthesizing benzothiazole compound by using copper complex

-

Paragraph 0056-0067, (2021/09/22)

The invention relates to a method for catalytically synthesizing benzothiazole compounds by using a copper complex, which is characterized in that a copper complex containing ortho-carborane Schiff base ligand is used as a catalyst to form aldehydes. 2 - Bromoaniline and sodium sulfide are used as raw materials, and the reaction is carried out at room temperature to obtain a benzothiazole compound. Compared with the prior art, the copper complex catalytic aldehyde, 2 -bromoaniline and sodium sulfide (Na) containing the ortho-carborane Schiff base ligand are utilized. 2 Multiple components of S) react to prepare benzothiazole compounds, and the catalyst is low in dosage, mild in reaction conditions, high in reaction rate, high in yield, wide in substrate range, cheap and accessible in raw materials and wide in application prospect in industry.

Sulfur-Promoted Redox Cyclization of 2,2′-Dinitrodiphenyl Disulfides and Benzylamines

Teramoto, Masahiro,Imoto, Mitsutaka,Takeda, Motonori,Mizuno, Takumi,Nomoto, Akihiro,Ogawa, Akiya

, p. 2485 - 2493 (2021/04/15)

This study aims to develop green and sustainable advanced synthetic methods based on redox cyclization. Elemental sulfur is shown to promote the efficient synthesis of 2-substituted benzothiazoles from 2,2′-dinitrodiphenyl disulfides and benzylamines via redox cyclization in the absence of transition-metal catalysts and solvents. The 2-substituted benzothiazoles are obtained in good to excellent yields. This synthetic methodology is highly atom-economical and does not require any external oxidizing and/or reducing agents.
