In 1972,Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya included an article by Kadentsev, V. I.; Chizhov, O. S.; Yanovskaya, L. A.; Kucherov, V. F.. Recommanded Product: Ethyl 3-(4-chlorophenyl)propanoate. The article was titled 《Oxygen rearrangement of aromatic and unsaturated acid esters. 4. Mass spectra of p- and m-substituted esters of β-phenylpropionic acid and their heterocyclic analogs》. The information in the text is summarized as follows:
The title mass spectra for meta and para isomers of XC6H4(CH2)2CO2Et (X = Me, MeO, Cl, Br, H), as well as analogs, revealed that the nature of X and its position in the ring both affected the fragmentation. The Class I groups did not interfere with the oxygen-rearrangement, with the meta isomers showing somewhat stronger orienting effect than the para isomers; substituents of Class II inhibited this rearrangement almost totally but did cause a similar rearrangement. Thus, the ester with a m-O2N group was converted to I, while the para isomer yielded II. Both were formed through an intermediate 6-atom ring transition state. In the part of experimental materials, we found many familiar compounds, such as Ethyl 3-(4-chlorophenyl)propanoate(cas: 7116-36-1Recommanded Product: Ethyl 3-(4-chlorophenyl)propanoate)
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. The haloform reaction, using chlorine and sodium hydroxide, is also able to generate alkyl halides from methyl ketones, and related compounds. Chloroform was formerly produced thus.Recommanded Product: Ethyl 3-(4-chlorophenyl)propanoate
