Abstract
An efficient and green synthesis of thiocarbamoyl-3,5-diaryl-4,5-dihydro-1 H-pyrazoles via the condensation of chalcones with thiosemicarbazide in ethanol and KOH under ultrasound irradiation is reported. The products were isolated in good yields after short reaction times. (C) 2009 Elsevier B.V. All rights reserved. (AU)
