A palladium‐catalyzed domino method for the direct synthesis of carbamates and ureas has been developed by using readily available and economical starting materials (aryl halide, carbon monoxide, sodium azide, amines, and alcohols) in a one‐pot approach. This efficient and phosgene‐free process provided an inexpensive and attractive route to synthesize the products in good to excellent yields.
通过一锅法使用容易获得且经济的起始原料(芳基卤化物,一氧化碳,叠氮化钠,胺和醇),已经开发了直接催化氨基甲酸酯和脲合成钯催化的多米诺骨牌方法。这种高效且无光气的工艺提供了一种廉价且诱人的途径,可以以良好的收率获得优良的合成产物。
