The long-chain alkenoic acid hydrazides (1a–d) on reaction with phenylisocyanate and phenylthiocyanate gave their corresponding semicarbazides (2a–d) and thiosemicarbazides (4a–d), which on further refluxing with POCl3 and Ac2O yielded corresponding 1,3,4-oxadiazoles (3a–d) and thiadiazoles (5a–d), respectively. The structure elucidation of synthesized compounds is based on the elemental analysis and
