Three unsymmetrical bridged terphthaloyl acetophenone oxime esters have been synthesized throughout an esterification process between three acetophenone oximes and the terphthaloyl chloride under mild basic conditions. Spectroscopic techniques, such as IR, HNMR and mass spectrometer, were used to confirm the structures of the desired oxime esters. The yields of the resulting oxime esters ranged from 50% to 73%.
A number of unsymmetrical bridged terphthaloyl acetophenone oxime esters has been synthesized throughout an esterification reaction between four different acetophenone oximes and the terphthaloyl chloride in a molar ratio of (2:1) under mild basic conditions. Spectroscopic techniques, such as IR, HNMR and mass spectrometer, were used to confirm the structures of the targeted oxime esters. The yields of the obtained oxime esters ranged from 80% to 95%.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
