Flower‐Like Au@CeO 2 Core‐Shell Nanospheres as Efficient Photocatalyst for Multicomponent Reaction of Alcohols and Amidines

Au@CeO2 flower-like core-shell nanospheres can be used as an efficient and recyclable photocatalyst to enhance the synthesis of 2,4,6-trisubstituted pyrimidines via the three-component reaction of alcohols and amidines. A synergistic effect between the ceria and gold on the photocatalytic transformation was found.
