Tetramethylbutadiene, also known as 2,3,3,4-tetramethyl-1,3-butadiene, is an organic compound with the chemical formula C8H12. It is a colorless liquid with a strong, pungent odor and is insoluble in water. This conjugated diene is characterized by its four methyl groups attached to the butadiene backbone, which contributes to its unique chemical properties. Tetramethylbutadiene is used as a monomer in the production of specialty polymers and as a chemical intermediate in the synthesis of various organic compounds. It is also known for its reactivity in Diels-Alder reactions, a type of chemical reaction used to form six-membered rings, making it a valuable building block in organic chemistry.

1187-40-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1187-40-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,8 and 7 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1187-40:
(6*1)+(5*1)+(4*8)+(3*7)+(2*4)+(1*0)=72
72 % 10 = 2
So 1187-40-2 is a valid CAS Registry Number.

Nickel-catalysed electrochemical coupling of 2- and 3-bromothiophene with alkyl and alkenyl halides

Durandetti, Muriel,Perichon, Jacques,Nedelec, Jean-Yves

, p. 8683 - 8686 (2007/10/03)

2- or 3-bromothiophene are efficiently coupled with activated alkyl chlorides (α-chloroesters, α-chloroketones, α-chloronitriles), benzyl chloride or vinyl halides, in a one step electrochemical reaction, using the sacrificial anode process and catalysis by NiBr2-2,2'-bipyridine (bipy).
