2-Chlor-bis-α-<2-chlor-phenyl>-zimtsaeure, also known as 2-chloro-2',4'-dichlorobiphenyl-4-acetic acid, is a chlorinated derivative of cinnamic acid. 2-Chlor-bis-α-<2-chlor-phenyl>-zimtsaeure features a cinnamic acid backbone with two chlorine atoms attached to the phenyl rings at the ortho and para positions relative to the carbonyl group. The presence of these chlorine atoms significantly alters the chemical properties and potential applications of the molecule. It is a synthetic organic compound that may be used in various chemical processes or as an intermediate in the synthesis of other compounds. Due to its chlorinated nature, it is important to consider its environmental impact and potential health risks, as chlorinated compounds can be persistent and bioaccumulative in the environment.

732-32-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 732-32-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,3 and 2 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 732-32:
(5*7)+(4*3)+(3*2)+(2*3)+(1*2)=61
61 % 10 = 1
So 732-32-1 is a valid CAS Registry Number.

Copper-catalyzed hydrocarboxylation of alkynes using carbon dioxide and hydrosilanes

Fujihara, Tetsuaki,Xu, Tinghua,Semba, Kazuhiko,Terao, Jun,Tsuji, Yasushi

supporting information; experimental part, p. 523 - 527 (2011/03/16)

Getting a fix: The copper-catalyzed hydrocarboxylation of alkynes using carbon dioxide in the presence of a hydrosilane, which serves as a reducing agent, has been developed (see scheme). Copper fluorides bearing N-heterocyclic carbene ligands such as IMes and Cl2IPr show high catalytic activities.
