Irradiation with ultrasound is found to facilitate the synthesis of 2-alkyl-2- alkoxy-1, 2-di(furan-2-yl)ethanone in the presence of tetrabutylammonium bromide (TBAB) as solid-liquid phase transfer catalysis. A higher yields (> 70%) and shorter reaction time (< 15 min) give this method obvious advantages over the conventional ones.
