Abstract

Synthetic and spectroscopic data (¹H NMR, ¹³C NMR, IR, UV/Vis) for a series of six 2,3-diphenyl-1,3-thiaza-4-one heterocycles which differ in ring size and substitution is reported. The results show that there are significant differences in spectroscopic signals common to all six compounds. Distinctions can be made among the compounds using the IR absorbance of the C4 carbonyl and the ¹H NMR signal at C2, and to a lesser extent the ¹³C NMR signal at C4 and the UV/Vis spectrum.
