The CC double bond cleavage of enaminones has been realized under ambient conditions through visible‐light catalysis in the presence of Rose Bengal, which leads to the synthesis of a class of 1,2‐diketones without using any metal catalyst. In addition, the one‐pot synthesis of quinoxalines has also been achieved under identical photocatalytic conditions by making use of the in situ generated 1,2‐diketones
在存在玫瑰红的情况下,通过可见光催化在环境条件下实现了烯胺酮的CC双键裂解,这导致无需使用任何金属催化剂即可合成一类1,2-二酮。此外,利用原位生成的1,2-二酮作为中间体,在相同的光催化条件下也可以完成一锅合成喹喔啉的合成。
