讲座摘要：

Alternating current (AC) electrolysis also can tune additional parameters such as the waveform, frequency, duty ratio and so on, which could lead to some advances in reaction development. Herein we present two AC electrolysis strategies aiming at different organic synthesis scenarios. One is AC-promoted metal-catalyzed electrolysis.¹ The long-standing challenge of noble metal catalyst reduction on the cathode during undivided electrolysis has been successfully addressed by utilized asymmetric-waveform alternating current electrolysis. Electrode types, current, AC frequency and duty ratio are important factors in regenerating the catalyst and adjusting the selectivity during AC electrolysis. Another is controlling reactive intermediates existence.^2,3 Due to the fast sine-waveform frequency, both oxidation and reduction processes could take place at the same electrode and even almost the same time along with the electrode polarity reversal. Therefore, AC electrolysis can control the formation of certain reactive intermediates via adjusting the frequency. Overall, AC electrolysis will pave new avenues to innovation in organic synthesis
