“…Asymmetric and quiet‐time waveforms come from symmetric types finely tuning AC parameters [9] . Although AC electricity has been widely applied in electro‐analysis and reaction kinetics studies, [10] it has been still underexplored for mainstream synthesis. Initial explorations into AC electrolysis were primarily motivated by curiosity, tracing their origins to the direct electrolysis of select organic molecules under AC conditions [11] .…”

Organic electrosynthesis has consistently aroused significant interest within both academic and industrial spheres. Despite the considerable progress achieved in this field, the majority of electrochemical transformations have been conducted through the utilization of direct‐current (DC) electricity. In contrast, the application of alternating current (AC), characterized by its polarity‐alternating nature, remains in its infancy within the sphere of organic synthesis, primarily due to the absence of a comprehensive theoretical framework. This minireview offers an overview of recent advancements in AC‐driven organic transformations and seeks to elucidate the differences between DC and AC electrolytic methodologies by probing into their underlying physical principles. These differences encompass the ability of AC to preclude the deposition of metal catalysts, the precision in modulating oxidation and reduction intensities, and the mitigation of mass transfer processes.
