Abstract
The one‐pot three component condensation of hydrazine hydrate with substituted phenylisothiocyanates followed by the addition of substituted benzaldehydes in the presence of ionic liquid 1‐butyl‐3‐methylimidazolium tetrafluoroborate ([bmim]BF4) and in the absence of any other catalyst under mild condition afforded 1,3,4‐thiadiazoles in excellent yields. The reaction workup is simple, and the ionic liquid was easily recovered from the reaction and reused. © 2008 Wiley Periodicals, Inc.
