Abstract: Rearrangement reactions are a key focus in undergraduate organic chemistry education. However, while ionic rearrangement reactions and pericyclic reactions are extensively covered, radical rearrangement reactions are rarely introduced in university curricula. This gap often results in an incomplete understanding of the subject by students. This article aligns with recent developments in the field and presents an overview of visible-light photocatalyzed radical rearrangement reactions, framed through the lens of functional groups, which undergraduates are well-prepared to grasp. By selecting representative reactions that are both illustrative and accessible to undergraduates, and by analyzing them from a mechanistic standpoint, this paper aims to bridge the gap between foundational teaching and cutting-edge chemistry. This approach not only addresses gaps in textbooks but also broadens students' knowledge, fostering their curiosity and enthusiasm for exploring the mysteries of chemistry.
