The relentless demand for diverse aromatic scaffolds, essential in fields ranging from material science to pharmaceuticals and agrochemicals, has driven the development of efficient aromatization reactions. The 20th century saw significant advancements in transition metal (TM) catalysis, leading to numerous metal-catalyzed systems for converting non-aromatic precursors into aromatic compounds. However, current research is increasingly guided by sustainability and green chemistry principles. This review provides a historical context for aromatization reactions and presents a comprehensive overview of metal-free methods, with a particular emphasis on the aromatization of carbocycles. The potential of these metal-free approaches to offer greener, more economically feasible alternatives to traditional methods is critically evaluated.
