base-free four-component Pd-catalyzed carbonylation of aryl halides in the presence of potassium cyanate and alcohols in a two-chamber system. This approach produces a wide range of aryl acyl carbamates in good to excellent yields from the corresponding aryl bromides or iodides with near-stoichiometric carbon monoxide. In addition, the method can be extended to the synthesis of primary amides thereby
在两腔室系统中,在氰酸钾和醇的存在下,通过无碱四组分钯催化的芳基卤化物的羰基化,证明了一种简单温和的氨基甲酸氨基酯的组装方法。该方法从相应的具有接近化学计量的一氧化碳的芳基溴化物或碘化物以良好或优异的产率产生了范围广泛的芳基酰基氨基甲酸酯。另外,该方法可以扩展到伯酰胺的合成,从而扩展了氰酸酯作为氨当量的用途。
