El-Bardan, Ali A.,Gohar, Gamal A.,El-Zahraa, Fatma,El-Hegazy, M.,Hamed, Ezzat A.

, p. 147 - 152 (2007/10/02)

New methyl and ethyl-3- benzoates and their corresponding phenyl sulfonyl derivatives have been synthesized and identified by UV, IR and 1H-NMR.Both phenylthio 1 and 2 as well as phenyl sulfonyl derivatives 3 and 4 showed a linear relationship between chemical shift δ ppm of the benzylic protons and ?-Hammett constants. Key words: Arylthio; aryl sulfonyl benzoates, 1H-NMR.
