摘　　要：The development of innovative and sustainable catalytic strategies for organic synthesis is a pivotal aspect of advancing material science and chemical engineering.This research presents a new catalytic method for the aminoacylation of N-sulfonyl ketimines by utilizing a potassium-doped graphite-like carbon nitride(g-C_(3)N_(4))framework.This method not only enhances the catalytic efficiency and broadens the light absorption spectrum of g-C_(3)N_(4)but also significantly reduces the recombination rate of electronhole pairs,thereby increasing the reaction yield and selectivity.Importantly,our approach facilitates the synthesis of aminoacylated N-heterocycles,expanding the applicability of potassium-modified g-C_(3)N_(4)in photocatalytic organic synthesis.A notable accomplishment of this study is the unprecedented generation of carbamoyl radicals via heterogeneous photocatalysis,which can be easily recycled after reaction.This advancement highlights the capability of potassium-doped g-C_(3)N_(4)(namely K-CN)as an advanced heterogeneous photocatalyst for the formation of complex organic compounds.
