Abstract:
(Un)substituted benzaldehyde (5‐aryl‐1,3,4‐thiadiazol‐2‐yl)hydrazones were efficiently synthesized by reactions of (un)substituted benzaldehyde thiocarbohydrazones with aromatic carboxylic acids by using silica‐supported dichlorophosphate as a recoverable dehydrant under microwave irradiation. The protocol has advantages of short reaction time, high yield, easy work‐up procedure and no environmental pollution.
