摘　　要：光与过渡金属协同催化的偶联反应为金属催化偶联反应的发展提供了新的研究策略.在这些催化体系中,激发态光敏剂通过单电子转移过程调节过渡金属中间体的价态,实现对偶联反应过程的调控,尤其是传统过渡金属催化体系中难以发生的反应.此外,激发态光敏剂也可以通过能量转移过程促进过渡金属催化偶联反应的进行.同时,无外加光敏剂参与光促进过渡金属催化的C-杂原子键偶联反应也得到了快速发展.光与过渡金属协同催化的偶联反应为构建C-杂原子键提供了重要方法,展示了在合成化学中广阔的应用前景.The photo-transition metal synergistically catalyzed coupling reaction provides a new research strategy for the development of metal-catalyzed coupling reactions.In this catalytic system,the excited state photosensitizer controls the valence state of the transition metal intermediate through a single electron transfer process,there by regulating the coupling reaction process,especially for the process that is difficult to occur in traditional transition metal catalysis.In addition,the excited photosensitizers could also promote the coupling reaction through the energy transfer process.Simultaneously,the light-promoted transition metal-catalyzed C—X bond coupling reactions without external photosensitizers have also been rapidly developed.Light and transition metals synergistically catalyzed coupling reactions provide an important tool for the construction of C-heteroatom bonds,showcasing broad application prospects in synthetic chemistry.
