(Z)-p-nitro-(1-propenyl)benzene, also known as β-nitrostyrene, is an organic compound with the chemical formula C9H9NO2. It is a yellowish oily liquid that is insoluble in water but soluble in organic solvents. (Z)-p-nitro-(1-propenyl)benzene is characterized by a nitro group (-NO2) attached to the para position of a benzene ring and a propenyl group (-CH=CH-CH3) attached to the same carbon atom. It is an important intermediate in the synthesis of various pharmaceuticals, dyes, and polymers. Due to its reactivity, it is used in the preparation of various derivatives, such as polymers with specific properties. The (Z)-isomer indicates the geometric arrangement of the double bond in the propenyl group, with the nitro group and the propenyl group on the same side of the double bond.

Check Digit Verification of cas no

The CAS Registry Mumber 1879-54-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,7 and 9 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1879-54:
(6*1)+(5*8)+(4*7)+(3*9)+(2*5)+(1*4)=115
115 % 10 = 5
So 1879-54-5 is a valid CAS Registry Number.

THE REACTION OF BENZYLTRIPHENYLARSONIUM YLIDES WITH ALDEHYDES. A NOTE ABOUT THE MECHANISM OF THE WITTIG REACTION.

Broos, Rene,Anteunis, Marc J. O.

, p. 271 - 280 (2007/10/02)

The products and stereochemistry of the reaction of the benzyltriphenyl arsonium ylide with benzaldehyde and acetaldehyde both in the presence of lithium salts and under salt-free conditions are studied by 1H NMR at 360 MHz.The stereochemistry is discussed in view of recent developments in the mechanistic interpretation of the Wittig and Johnson-Corey-Chaykovsky reaction.
