摘要

Abstract A method of preparing 2, 5-disubstituted 1, 3, 4-oxadiazoles from benzoyl isothiocyanates and 5-substituted tetrazoles is described. The transformation of the tetrazole into a 1, 3, 4-oxadiazole ring takes place readily under neutral conditions giving high yields of the desired products.
