The author of 《Intramolecular interactions. Dipole moments and rotational isomerism of a series of 1-substituted 2-arylethanes》 were Camail, Michel; Dicko, Dankoulodo D.. And the article was published in Comptes Rendus des Seances de l’Academie des Sciences, Serie C: Sciences Chimiques in 1971. COA of Formula: C11H13ClO2 The author mentioned the following in the article:
The dipole moments are determined for 12 p-AC6H4CH2CH2X (A = H, Me, Cl; X = Cl, Br, CN, CO2-Et) and used to estimate the anti-gauche isomer equilibrium In the experiment, the researchers used Ethyl 3-(4-chlorophenyl)propanoate(cas: 7116-36-1COA of Formula: C11H13ClO2)
Ethyl 3-(4-chlorophenyl)propanoate(cas: 7116-36-1) belongs to organochlorine compounds. Alkanes and aryl alkanes may be chlorinated under free radical conditions, with UV light. COA of Formula: C11H13ClO2 However, the extent of chlorination is difficult to control. Aryl chlorides may be prepared by the Friedel-Crafts halogenation, using chlorine and a Lewis acid catalyst.
