Amberlyst-15 and Amberlite-200C: efficient catalysts for aldol and cross-aldol condensation under ultrasound irradiation. | LitMetric
This paper presents an improved synthesis of trans-chalcones and α,α'-bis(arylmethylidene) cycloalkanones under ultrasound irradiation in the presence of commercial acid-resins as catalysts in solvent free conditions. Several trans-chalcones and α,α'-bis(arylmethylidene) cycloalkanones were synthesized in good yields and excellent selectivity in a short reaction time.
