Benzene, 1,3-dichloro-2-(2,2-dichloroethenyl)-, also known as 1,3-dichloro-2,2-dichlorovinylbenzene, is an organochlorine compound with the chemical formula C8H4Cl4. It is a colorless liquid with a pungent odor and is used as an intermediate in the production of various chemicals, including pesticides and flame retardants. Benzene, 1,3-dichloro-2-(2,2-dichloroethenyl)- is characterized by its benzene ring structure, with two chlorine atoms attached to carbon atoms at positions 1 and 3, and a dichloroethene group (CCl2=CH2) attached to the carbon at position 2. Due to its chemical structure, it exhibits properties such as low solubility in water and high solubility in organic solvents. It is important to note that Benzene, 1,3-dichloro-2-(2,2-dichloroethenyl)- is considered hazardous due to its potential health and environmental risks, and appropriate safety measures should be taken when handling it.

Check Digit Verification of cas no

The CAS Registry Mumber 5281-25-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,8 and 1 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 5281-25:
(6*5)+(5*2)+(4*8)+(3*1)+(2*2)+(1*5)=84
84 % 10 = 4
So 5281-25-4 is a valid CAS Registry Number.

Conversion of aromatic aldehydes into 1-aryl-2,2-dichloroethenes

Nenajdenko,Shastin,Korotchenko,Balenkova

, p. 1047 - 1050 (2001)

A new general one-pot preparative method for the synthesis of 1-aryl(hetaryl)-2,2-dichloroethenes from aldehydes was developed. The method involves successive conversions of the latter into hydrazones followed by treatment with carbon tetrachloride in the

A novel synthetic approach to dichlorostyrenes

Shastin,Korotchenko,Nenajdenko,Balenkova

, p. 6557 - 6563 (2007/10/03)

We found that N-unsubstituted hydrazones of aromatic aldehydes can be easily converted to the corresponding 1,1-dichlorostyrenes in the reaction with carbon tetrachloride using copper (I) chloride as catalyst. Factors affecting the route of the reaction and yields of the products were investigated. A proposed mechanism for the reaction is discussed. (C) 2000 Published by Elsevier Science Ltd.
