Synthesis of Some Bridged Unsymmetrical Terphthaloyl Oxime Esters

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%.
