Abstract: The Catellani reaction is a named reaction in palladium catalysis that leverages palladium/norbornene cooperative catalysis to achieve sequential ortho C–H functionalization of aryl halides and ipso coupling at the halogen site, thereby enabling the efficient construction of polysubstituted arenes. This article introduces its discovery background, catalytic mechanism, research progress, and representative applications in the total synthesis of natural products, and discusses its value in undergraduate organic chemistry education, with the aim of providing a reference for organic chemistry teaching and research practice.
