Published as part of the Special Topic Modern Coupling Approaches and their Strategic Applications in Synthesis Abstract A new and efficient method for the synthesis of 1,3,4-oxadiazoles via the annulation of hydrazides with benzene-1,3,5-triyl triformate (TFBen) under metal-free conditions is reported. A broad range of hydrazides were transformed into
