Benzene, 1,4-bis[2-(4-methylphenyl)ethyl]-, also known as 1,4-bis(4-methylbenzyl)benzene or 1,4-di(4-methylbenzyl)benzene, is an organic compound with the molecular formula C19H20. It is a symmetrical, planar molecule consisting of a central benzene ring with two 4-methylbenzyl groups attached to the 1 and 4 positions. The 4-methylbenzyl groups are themselves composed of a benzene ring with a methyl group attached to the para position (4-position). Benzene, 1,4-bis[2-(4-methylphenyl)ethyl]- is a type of biphenyl derivative, characterized by the presence of two benzene rings connected through an alkyl chain. It is an aromatic hydrocarbon with potential applications in the synthesis of various organic compounds and materials, such as polymers and pharmaceuticals.

2962-72-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2962-72-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,6 and 2 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 2962-72:
(6*2)+(5*9)+(4*6)+(3*2)+(2*7)+(1*2)=103
103 % 10 = 3
So 2962-72-3 is a valid CAS Registry Number.

Samarium(II) Diiodide Mediated Coupling of Bis(bromomethyl)arenes. Facile Synthesis of n>Cyclophanes without using High-Dilution Techniques

Takahashi, Senji,Mori, Nobuo

, p. 2029 - 2032 (2007/10/02)

In the presence of samarium(II) diiodide (Sml2), coupling of 1,3- and 1,4-bis(bromomethyl)benzenes proceeds smoothly to give their cyclic and acyclic oligomers.Use of 1.2 equiv. of Sml2 gives 1,2-bis(3- and 4-bromomethylphenyl)ethanes, respectively, in 95percent yield, and the use of 5.0 equiv. of Sml2 affords n>metacyclophanes and n>paracyclpphanes (n = 2, 3 and 4), respectively, in satisfactory yields.By using 5.0 equiv. of Sml2, 2-bromo- and 2-methoxy-1,4-bis(bromomethyl)benzenes and 1,4- and 2,6-bis(bromomethyl)naphthalenes each give only one of several expected isomeric cyclophanes as the major cyclic oligomer.
