(E)-2-(3-chlorophenyl)-1-(4-chlorophenyl)ethene, also known as 1,2-bis(3-chlorophenyl)ethene, is an organic compound characterized by a double bond between two phenyl rings, each substituted with a chlorine atom at different positions. Specifically, one phenyl ring has a chlorine atom at the 3rd position, while the other has a chlorine atom at the 4th position. This chemical structure endows the molecule with unique electronic and steric properties, which can influence its reactivity and physical characteristics. The compound is a colorless to pale yellow solid and is used in various chemical syntheses, particularly in the production of pharmaceuticals and agrochemicals. It is important to handle (E)-2-(3-chlorophenyl)-1-(4-chlorophenyl)ethene with care due to its potential toxicity and environmental impact.

Check Digit Verification of cas no

The CAS Registry Mumber 25144-36-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,1,4 and 4 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 25144-36:
(7*2)+(6*5)+(5*1)+(4*4)+(3*4)+(2*3)+(1*6)=89
89 % 10 = 9
So 25144-36-9 is a valid CAS Registry Number.

Ligand-controlled iridium-catalyzed semihydrogenation of alkynes with ethanol: highly stereoselective synthesis of E- and Z-alkenes

Yang., Jinfei,Wang, Chengniu,Sun, Yufeng,Man, Xuyan,Li, Jinxia,Sun, Fei

supporting information, p. 1903 - 1906 (2019/05/02)

A ligand-controlled iridium-catalyzed semihydrogenation of alkynes to E- and Z-alkenes with ethanol was developed. Effective selectivity control was achieved by ligand regulation. The use of 1,2-bis(diphenylphosphino)ethane (DPPE) and 1,5-cyclooctadiene (COD) was critical for the stereoselective semihydrogenation of alkynes. The general applicability of this procedure was highlighted by the synthesis of more than 40 alkenes, with good stereoselectivities. The value of our approach in practical applications was investigated by studying the effects of pinosylvin and 4,4′-dihydroxystilbene (DHS) on zebrafish as a vertebrate model.
