Abstract

Abstract A series of oxazoline compounds have been prepared by reaction of 2, 6-diformyl-4- chlorophenol, 2, 6-diformylpyridine or 2, 5-diformylthiophen with o-aminophenol or o- aminothiophenol respectively. The oxazoline derivatives are stable both in solid state and in solution while the thiazoline derivatives easily oxidize to the corresponding thiazoles. Physico-chemical data confirm this oxidation process. The 70 eV electron impact induced ...
