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 as intermediates.
