Abstract
Near-ultraviolet and visible light-induced organic synthesis without photosensitizer has attracted much attention for the organic chemists. Since no photosensitizer is needed in the reaction, it makes the reaction system more simple and feasible, and indicates the future development direction for visible-light-induced organic transformations. Visible-light-promoted organic synthesis without photosensitizer is reviewed in this paper. It covers organic photosyntheses in which the substrate/product as a light-absorbing substance, the electron donor acceptor (EDA) complex as a light-absorbing substance, and the homolysis of weak covalent chemical bonds under the visible-light irradiation conditions. Moreover, other organic photosynthetic reactions without external photocatalyst are also discussed.
