Anhydrous zinc chloride catalysed synthesis of 2-phenyl-4-arylidene-5(4H)-oxazolones

An improved procedure is reported for the synthesis of arylidene oxazolones from hippuric acid and aromatic aldehydes in the presence of acetic anhydride and anhydrous zinc chloride in 62-76percent yields.

Studies on Infrared Spectra of some Azalactones

Infrared spectra of some 4-(p-substituted-benzylidene)-2-phenyl-5-oxazolones have been studied with reference to frequency of CN and C=O groups of the ring, which were not significantly influenced by variations of the para-substituent.
