practical synthesis of aryl and heteroaryl N‐acylureas has been developed via palladium‐catalysed carbonylation of aryl or heteroaryl halides in the presence of urea nucleophiles. A range of reactions illustrating the wide scope of this reaction was carried out under microwave irradiation, using either carbon monoxide gas in a vessel equipped with a gas inlet adapter, or molybdenum hexacarbonyl as the
在脲亲核试剂的存在下,通过钯催化的芳基或杂芳基卤化物的羰基化反应,已开发出一种新的实用的芳基和杂芳基N-酰基脲合成方法。说明反应的广泛范围的一系列反应是在微波辐射下进行的,使用一氧化碳气体在装有进气口适配器的容器中,或六羰基钼作为标准微波小瓶中的一氧化碳源。反应以良好至优异的产率进行。为了说明该方法的有效性,报告了重要杀虫剂双氟苯隆的一步合成方法。
