Butt, G.; Topsom, R. D. published an article in Spectrochimica Acta, Part A: Molecular and Biomolecular Spectroscopy. The title of the article was 《Transmission of substituent effects through extended systems. III. p-Substituted ethyl trans-cinnamates and phenylpropiolates》.Electric Literature of C11H13ClO2 The author mentioned the following in the article:
IR and 13C chem. shifts were determined for Et p-substituted trans-cinnamates and Et phenylpropiolates. The IR data include intensities for the benzene, ethylene, and CO group vibrations which allow an estimation of resonance effects. The relative importance of the various mechanisms of transmission of substituent effects is discussed and compared with those previously reported for p-substituted trans-cinnamonitriles. The CC is less efficient in transmitting substituent effects than the C:C. In the part of experimental materials, we found many familiar compounds, such as Ethyl 3-(4-chlorophenyl)propanoate(cas: 7116-36-1Electric Literature of C11H13ClO2)
Ethyl 3-(4-chlorophenyl)propanoate(cas: 7116-36-1) belongs to organochlorine compounds. The wide structural variety and divergent chemical properties of organochlorides lead to a broad range of names, applications, and properties.Electric Literature of C11H13ClO2 Aliphatic organochlorides are often alkylating agents as chlorine can act as a leaving group, which can result in cellular damage.
