Recent advances in electroreductive dearomatization of aromatic compounds

-rich architectures using electrons as traceless reductants. Compared with classical dissolving-metal reductions, electrochemical approaches offer improved safety, tunability, chemoselectivity and functional-group tolerance. This review summarizes advances from 2019 to 2026, focusing on Birch-type electroreduction, electrochemical hydrogenation/deuteration and dearomative electroreductive coupling. Key developments, including rapid alternating polarity electrolysis, electrocatalytic hydride/deuteride transfer, radical-anion chemistry, Lewis acid activation and tandem C-C bond formation, are discussed. Remaining challenges and opportunities in asymmetric reactions, site selectivity, paired electrolysis and flow scale-up are also highlighted.
