Di-tert-butyl-, di(1-adamantyl)- and (1-adamantyl)-tert-butylketenes were prepared in excellent yield from their corresponding acetyl chlorides with triethylamine under ultrasonic irradiation, showing a dramatic improvement over attempted conventional dehydrochlorination.
在超声波辐照下,用三乙胺从相应的乙酰氯中制备出了二叔丁基、二(1-金刚烷基)和(1-金刚烷基)叔丁基烯酮,收率极高,与传统的脱氢氯化法相比,效果显著。
