原子经济性是绿色化学中的一条重要原则,本文列举了一些重排反应在绿色化学工业中的地位和作用,并与其他的反应路线从原子经济性的角度进行了评述。由于该类反应具有原料利用率高,不生成对环境不友好的产物等独特优点,所以有着诱人的应用前景。最后对21世纪原子经济性反应的发展作了展望。 Atomic economy is an important principle in green chemistry. This article lists some of the rearrangement reactions in the green chemical industry status and role, and with other reaction routes from the perspective of atomic economy were reviewed. This kind of reaction has the attractive application prospect because of its unique advantages such as high utilization rate of raw materials and no environmentally unfriendly products. Finally, the development of atomic economy response in the 21st century is prospected.
