Abstract: The synthesis of a few 1,3,4-oxadiazoles 5a-e is described. 4- Fluoro-3-phenoxybenzoic acid 2 is prepared starting from 4-Fluoro-3- phenoxybenzaldehyde 1. Esterification of 2 with methanol in the presence of H2SO4 gives the corresponding ester 3. Hydrazinolysis of 3 with hydrazine hydrate results in acid hydrazide 4. Hydrazide on reaction with aryl acid chlorides in presence of POCl3 affords oxadiazoles 5a-e. The compounds 5b-e manifest low insecticidal activity against certain crop pests.
