摘要/Abstract

摘要： 金属有机化学教学需兼顾经典理论与前沿进展。本文建议将“激发态钯化学”引入课堂，以可见光介导激发态钯催化的Heck反应为例，通过与基态双电子型Heck反应对比，阐释涉及单电子转移过程的新型机理，帮助学生理解催化机理的多样性，提升科学思维。同时，结合我国学者贡献融入课程思政，增强学科自信，为培养创新人才提供新视角。

Abstract: The instruction of organometallic chemistry necessitates the integration of fundamental theories with contemporary research developments. This article advocates for the incorporation of “excited-state palladium chemistry” into undergraduate curricula, employing the visible-light-mediated excited-state palladium-catalyzed Heck reaction as a paradigm. Through comparative analysis with the conventional ground-state, two-electron Heck reaction, this approach elucidates the novel single-electron transfer mechanism, thereby facilitating students’ comprehension of catalytic mechanism diversity and fostering advanced scientific reasoning. Furthermore, by incorporating significant contributions from Chinese researchers, this pedagogical strategy effectively combines ideological education with professional training, enhances disciplinary confidence, and provides innovative perspectives for cultivating the next generation of chemists.
