Improved synthesis and characterisation of 1,3,4-oxadiazole

Abstract

Synthetic approaches to 1,3,4-oxadiazole have been investigated and an improved method involving dehydration of N,N′-diformylhydrazine with P2O5 in polyphosphoric acid is described. The 13C NMR spectrum of this compound is reported for the first time including determination of 1JC-H and 3J C-H. © ARKAT-USA, Inc.
