Solvent free synthesis of 1,3-diaryl-2-propenones catalyzed by commercial acid-clays under ultrasound irradiation
摘要:
This paper presents a novel solvent free method of synthesis of trans-chalcones. The method was based on ultrasound irradiation of the reagents (aryl methyl ketones and aryl aldehydes) in presence of commercial acid-montmorillonites as catalysts. The trans-chalcones were synthesized in high yields (85-95%) and excellent selectivity in a short reaction time. (C) 2009 Elsevier B.V. All rights reserved.

An efficient and regioselective hydrodehalogenation of aromatic α‐ and β‐halo carbonylcompounds has been developed using CuI in isopropanol under basic condition. This reaction system effectively reduces chloride, bromide and iodide groups and affords high yield (up to 97 %) as carbonylcompounds. The method is environmentally friendly and demonstrates excellent tolerance to a broad range of electronically
