(E)-1-methyl-2-(1-phenylprop-1-enyl)benzene, also known as β-methylstyrene or 2-phenyl-2-methyl-1-propene, is an organic compound with the molecular formula C??H??. It is a conjugated diene, featuring a methyl group attached to the benzene ring and a phenylpropenyl group (a phenyl group attached to a propene chain) at the 2-position. (E)-1-methyl-2-(1-phenylprop-1-enyl)benzene is an isomer of α-methylstyrene, differing in the position of the methyl group on the benzene ring. β-methylstyrene is an important intermediate in the synthesis of various chemicals and polymers, such as polystyrene and styrene-based copolymers. It is typically synthesized through various methods, including the Friedel-Crafts alkylation of toluene with propene or the dehydrogenation of 2-phenyl-2-methylpropane. Due to its conjugated system and aromatic character, β-methylstyrene exhibits unique chemical properties and reactivity, making it a valuable compound in the field of organic chemistry and materials science.

Check Digit Verification of cas no

The CAS Registry Mumber 4333-81-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,3,3 and 3 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 4333-81:
(6*4)+(5*3)+(4*3)+(3*3)+(2*8)+(1*1)=77
77 % 10 = 7
So 4333-81-7 is a valid CAS Registry Number.

Microwave-assisted, Pd(0)-catalyzed cross-coupling of diazirines with aryl halides

Zhao, Xia,Wu, Guojiao,Yan, Chong,Lu, Kui,Li, Hui,Zhang, Yan,Wang, Jianbo

supporting information; experimental part, p. 5580 - 5583 (2011/02/23)

Pd(0)-catalyzed cross-coupling reactions of diazirines with aryl halides under microwave heating conditions afford a series of substituted olefins. A reaction mechanism involving the migratory insertion of the Pd carbene intermediate is proposed.

Formation and rearrangement of gem-dilithiodiphenylethene

Maercker, Adalbert,Boes, Benno,Hajgholipour, Mohammad Taghi

, p. 143 - 149 (2007/10/03)

1,1-Dilithio-2,2-diphenylethene (14) is accessible through double bromine lithium exchange reaction starting from 1,1-dibromo-2,2-diphenylethene (5) with lithium metal at -110°C. 14 undergoes rearrangement into (E)-1-lithio-2-(2-lithiophenyl)-2-phenylethene (13) at temperatures above -100°C. The (Z)-compound 15 was formed from the (E)-compound 13 at temperatures above -25°C.
