Abstract

1,5-Diarylpenta-2,4-dien-1-ones were synthesized with ultrasound irradiation in the presence of activated barium hydroxide as catalyst. Compared to conventional methods, the present methodology offers several advantages such as excellent yields, simple procedure, short reaction times, and milder conditions.
