Abstract The transition metal catalyzed coupling reaction has revolutionized the strategies for forging carbon‐carbon bonds. In contrast to traditional cross‐coupling methods using pre‐prepared nucleophilic organometallic reagents, reductive reactions C−C bonds formation provide some advantages. Because both partners are reduced in final products a stoichiometric amount of reductant, this approach not only avoids need use sensitive species, but also provides an orthogonal and complementary access classical reaction. Notably, feature readily available fragments, promote good step economy, exhibit high functional group tolerance unique chemoselectivity, which have propelled their increasingly popular organic synthesis. recent years, due low price, minimal toxicity, environmentally benign character, iron‐catalyzed garnered significant attention from synthetic chemists pharmacologists, especially coupling. This review aims insightful overview advances reactions, illustrate possible mechanisms.

Reductive radical dearomatization N-alkyl quinoline quaternary ammonium salts to synthesize structurally complex and challenging polysubstituted benzo[d][1,3]oxazocines was first reported. The mechanism showed various allyl alcohols can be converted into alkyl radicals under reduction conditions of iron/silane. These then nucleophilically attack the C4 site salts, intramolecular cyclization resulting intermediate generates target product. This method not only produced a series novel but also prepared polycyclic benzo[d][1,3]oxazocines. Finally, this strategy made up for lack reductive reports on N-alkylquinolinium had advantages mild reaction conditions, wide substrate range, product structure.

A cyanoalkyl-hydroxylation reaction of aryl alkenes has been successfully devised, employing ferrocene as a catalyst for the addition cycloketone oxime ester and H2O across double bond alkene. This environmentally friendly approach employs solvent mixture consisting water demonstrates redox neutrality, along with exceptional regio- chemoselectivity, leading to formation diverse distal hydroxy-nitrile compounds. Moreover, this research presents noteworthy contributions in terms late-stage functionalization complex molecules offers valuable insights into mechanistic aspects reaction.
