Sonoelectrochemistry - Cyclohexanoate electrooxidation at 38 kHz and 850 kHz insonation frequencies compared

Insonation of cyclohexanoate electrooxidation at platinum in methanol produces a similar switch in product distribution from one-electron per-molecule dimers towards products from the two-electron route via the carbocation, irrespective of whether the ultrasonic bath employs 38 or 850 kHz frequencies. However, 850 kHz produces a cleaner reaction and higher yields, with more than two-fold greater yield of total extracted products over the silent system, and one-and-a-half times yield enhancement over insonation at 38 kHz.
