(Z)-1,2-Bis(4-chlorophenyl)-1,2-dichloroethene, also known as 4,4'-Dichlorobenzophenone or DCBP, is an organochlorine compound with the chemical formula C14H8Cl4. It is a colorless to pale yellow crystalline solid with a molecular weight of 320.03 g/mol. DCBP is primarily used as a chemical intermediate in the production of various pesticides, such as the herbicide 2,4-Dichlorophenoxyacetic acid (2,4-D). It is also used as a flame retardant and a plasticizer. Due to its potential health and environmental risks, including its classification as a probable human carcinogen, the production and use of DCBP have been restricted or banned in several countries.

5216-27-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5216-27-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,1 and 6 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 5216-27:
(6*5)+(5*2)+(4*1)+(3*6)+(2*2)+(1*7)=73
73 % 10 = 3
So 5216-27-3 is a valid CAS Registry Number.

CONVERSION OF DISILANES TO FUNCTIONAL MONOSILANES. XIII. THE PALLADIUM CATALYZED REDUCTIVE COUPLING OF BENZYLIDENE DICHLORIDES AND BENZYLIDYNE TRICHLORIDES USING DISILANES AS REDUCING AGENTS.

Matsumoto,Arai,Takahashi,Ashizawa,Nakano,Nagai

, p. 3009 - 3014 (2007/10/02)

The reaction of benzylidene dichlorides or benzylidene trichlorides with 1,2-dichloro-1,1,2,2-tetramethyl-disilane or hexamethyldisilane proceeded smoothly in the presence of a catalytic amount of Pd(PPh//3)//4 to give (E)-stilbenes or (E)- and (Z)- alpha beta -dichlorostilbenes in high yields, respectively. Also, in the presence of the palladium (0) catalyst, alpha , alpha -dichlorobenzyltrimethylsilanes reacted with hexamethyldisilane yielding (E)- alpha , beta -bis(trimethylsilyl)stilbenes in quantitative yield.
