光催化有机物偶联/芳构化放氢反应研究进展

Progress on the Photocatalytic Organic Hydrogen-Evolution Coupling/Aromatization Reaction

光催化氧化还原反应具有绿色、高效、安全等优势,已经在有机化学中得到广泛关注.介绍了基于光催化的偶联/芳构化放氢反应,通过使用光催化剂/催化剂的双催化体系,可用于光催化有机碳-碳和碳-杂原子成键反应,且反应中氢气是唯一的副产物.强调了有机光氧化还原体系的构建与催化机理.

The photocatalytic redox reactions have been widely concerned in organic chemistry due to their green, efficiency and safety. In this review, the cross-coupling/aromatization reactions are described based on photocatalytic organic hydrogenevolution, which can be used to build organic carbon-carbon and carbon-heteroatom bonds by using a photocatalyst/catalyst dual catalytic system. Hydrogen is the only by-product in these reactions. The system and catalytic mechanisms of organic photocatalytic redox reaction are highlighted.
