Abstract
A variety of 5-substituted-1,3,4-oxadiazole-2(3H)-thiones were prepared using microwave irradiation as energy source under solvent-free conditions. Reaction times were reduced from 5-14 h to 3-7 min affording high yields from corresponding acyl and aroyl hydrazides.
Keywords: microwave-assisted synthesis, 4-oxadiazolethiones, 5-substituted-1,3
