40231-48-9 Usage

General Description

1-Isopropyl-4-(2-phenylvinyl)benzene is a chemical compound with the formula C18H18. It is also known as Isosafrole and is commonly used in the synthesis of various drugs and fragrance compounds. It is a colorless to pale yellow liquid with a sweet, floral odor and insoluble in water. Isosafrole is a precursor to the psychoactive drug MDMA, also known as ecstasy, and is regulated due to its potential use in illegal drug production. It is also used in the production of fragrances and flavors and has been studied for its potential use in the medical and pharmaceutical industries. However, it is important to note that the use and handling of Isosafrole should be strictly regulated and controlled to prevent its misuse in illegal drug production.

Check Digit Verification of cas no

The CAS Registry Mumber 40231-48-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,2,3 and 1 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 40231-48:
(7*4)+(6*0)+(5*2)+(4*3)+(3*1)+(2*4)+(1*8)=69
69 % 10 = 9
So 40231-48-9 is a valid CAS Registry Number.

Synthesis of 1,2-diarylethylenes by Pd-catalyzed one-pot reaction of benzyl halides, tosylhydrazide, and aryl aldehydes

Shen, Xu,Liu, Ping,Liu, Yan,Dai, Bin

, p. 709 - 715 (2018/07/14)

Background: Substituted olefins are versatile functional groups and intermediates in chemistry, medicine, electronics, and optics and materials science fields because of their unique properties. One important class of substituted olefins 1,2-diarylethylenes have attracted considerable attention due to their presence in both natural products and pharmacologically active substances. Methods: In this paper, we developed a one-pot two-step coupling reaction of aryl aldehydes, tosylhydrazide with benzyl halides by using inexpensive Pd(PPh3)4 as catalyst, leading to a variety of 1,2- diphenylethenes derivatives with moderate to good yields. Results: The desired 1,2-diarylethylenes were obtained in 46-96% yields via Pd(0)-catalyzed one-pot reaction of benzyl halides, tosylhydrazide, and aryl aldehydes. Conclusion: The catalytic system presented here enables the use of easily accessible starting materials and good functional group tolerance.

Suzuki and Heck coupling reactions mediated by palladium complexes bearing trans-spanning diphosphines

Smith, Rhett C.,Bodner, Christina R.,Earl, Meredith J.,Sears, Nathaniel C.,Hill, Nicholas E.,Bishop, Lee M.,Sizemore, Nicholas,Hehemann, Dave T.,Bohn, Justin J.,Protasiewicz, John D.

, p. 477 - 481 (2007/10/03)

Palladium complexes of three trans-spanning diphosphines are examined for effecting C-C coupling reactions. Ten aryl halides of varying electron density were screened in Suzuki coupling reactions with phenylboronic acid and in Heck reactions with styrene.

A highly active and stereoselective montmorillonite catalyst for arylation of conjugated alkenes

Choudary, Boyapati M.,Sarma, Ravichandra M.,Rao, Koteswara K.

, p. 719 - 726 (2007/10/02)

A highly active and stereoselective heterogenised homogeneous catalyst montmorilloniteethylsilydiphenylphosphinepalladium (II) chloride complex (Pd/P is 1:1) for arylation of conjugated alkenes is reported.
