Intermolecular (3 + 2) annulation emerges as a potent approach for constructing 5-membered carbocycles through the fusion of two distinct components. This synopsis encapsulates recent strides in realm transition-metal-catalyzed dehydrogenative aromatic hydrocarbons, achieved dual functionalization benzylic and ortho C–H bonds. Encompassing three pivotal strategies, namely, (i) bond activation, (ii) oxidation, (iii) π-coordination this review offers an overview field's developments.

Abstract The radical difunctionalization of unsaturated hydrocarbons serves as an efficient means to rapidly construct molecular skeletons and synthesize‐highly valuable compounds. In this transformational process, diverse positions within are sequentially functionalized by a single precursor reagent, thereby achieving highly selective transformations that promote atom economy. Furthermore, approach minimizes the generation numerous byproducts stemming from cross‐coupling reactions between reactants, owing reduction number participating components. Therefore, review provides in‐depth analysis utilizing functional reagent in recent decades. discussion is based on eight different classes (carbon‐, nitrogen‐, phosphine‐, oxygen‐, sulfur‐, selenium‐, tellurium‐, chlorine‐centered radicals), emphasizing mechanism specific difunctionalization. It also analyzes detail regulation key factors such regional selectivity, unique insights into reaction transformations.
