在四氯化碳/水双相介质中，用卤化钾进行了一种新型的、温和的“声卤化”反应。可行性研究首先是对溴化钾进行的，然后扩展到氯化物和碘化物类似物。该方法与四氯化碳的声溶消失相联系，可被认为是超声高级氧化工艺（UAOPs）在合成方面的新扩展。本方法的优点不仅在于溴化操作简单、绿色，而且所使用的卤化剂容易获得、价格低廉、易于处理。(C) 2015 Elsevier B.V.版权所有
A novel, mild "sono-halogenation" of various aromatic compounds with potassium halide was investigated under ultrasound in a biphasic carbon tetrachloride/water medium. The feasibility study was first undertaken with the potassium bromide and then extended to chloride and iodide analogues. This methodology could be considered as a new expansion of the ultrasonic advanced oxidation processes (UAOPs) into a synthetic aspect as the developed methodology is linked to the sonolytic disappearance of carbon tetrachloride. Advantages of the present method are not only that the manipulation of the bromination is simple and green, but also that the halogenating agents used are readily available, inexpensive, and easy-handling.
