Thiophene, 2-bromo-5-(chloromethyl)-, is a chemical compound with the molecular formula C5H4BrClS. It is a halogenated derivative of thiophene, a heterocyclic compound consisting of a five-membered ring with one sulfur atom and four carbon atoms. The compound features a bromine atom at the 2-position and a chloromethyl group at the 5-position, which are both halogenated substituents. Thiophene, 2-bromo-5-(chloromethyl)-, is an important intermediate in the synthesis of various pharmaceuticals, agrochemicals, and other organic compounds due to its unique reactivity and functional group versatility. It is typically synthesized through the bromination and chloromethylation of thiophene, and its properties, such as solubility and stability, can be influenced by the presence of these halogenated substituents.

7311-46-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7311-46-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,3,1 and 1 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 7311-46:
(6*7)+(5*3)+(4*1)+(3*1)+(2*4)+(1*6)=78
78 % 10 = 8
So 7311-46-8 is a valid CAS Registry Number.

Palladium-catalyzed regioselective allylation of five-membered heteroarenes with allyltributylstannane

Zhang, Sheng,Yu, Xiaoqiang,Feng, Xiujuan,Yamamoto, Yoshinori,Bao, Ming

, p. 3842 - 3845 (2015)

Palladium-catalyzed allylation reactions of 2-(chloromethyl)thiophenes, 2-(chloromethyl)furans, and N-protected 2-(chloromethyl)-1H-pyrroles with allyltributylstannane were described in this study. This type of allylation reaction regioselectively occurred on the heteroarene rings to produce allylated dearomatization products or allylated heteroarenes with satisfactory yields.
