“…The coupling of US to EO constitute a thriving field gathering the mechanical effects of ultrasound (activation of the electrodes' surface and enhancement of the solid-liquid mass transfer) and their chemical effects (possible change in the degradation mechanisms) (Trabelsi et al, 1996;Lindermeir et al, 2003;Valcarel et al, 2004;. The optimization of ultrasound frequency is essential and highly depends on the contaminant to be treated.…”

Thiophene S-oxides constitute a class of molecules that have been studied in more detail only recently. Their existence as intermediates in the peracid mediated oxidation of thiophenes to thiophene S,S-dioxides, however, has been known over some time. Over the last 20 years, a larger number of thiophene S-oxides have been prepared and isolated in pure form. Thiophene S-oxides have been found to be good dienes in [4 + 2]-cycloaddition reactions, where they react with electron-poor, electron-neutral and electron-rich dienophiles with high syn π-facial stereoselectivity. Thiophene S-oxides have been found to be metabolites of thienyl-containing pharmaceuticals such as the anti-platelet drugs ticlopidine and clopidogrel. The chapter gives an overview of the preparation and reactivity of this class of compounds.

“…Valcarel et al 102 analyzed the ultrasound effects on the thiophene S-oxides' electrooxidation. Sonovoltamograms with 40 and 850 kHz bath insonation showed the expected current increases for tetraphenylthiophene S-oxide and tetracyclone.…”

The application of ultrasound with electrochemistry in organic chemistry (known as organic sonoelectrochemistry) accelerates the activation process of chemical reactions. This hybrid technology enhances electrical efficiency and modifies and increases the product yield. Moreover, it facilitates the mass transfer phenomena and the processes of cleaning, degassing, and activation of the electrode surfaces; maintains higher current densities for efficient chemical transformations; and also works efficiently for mixing of reactants in multiphase systems. The ultrasound technology has a prominent effect in heterogeneous reaction systems especially during the solid (electrode)–liquid (electrolytic mixture) interfacial cavitation process. The ultrasound technology gains attention due to its fundamental and positive effect in organic chemistry to make possible the challenging electrosynthetic processes. Herein, we report the sonoelectrosynthetic methods that will help researchers to understand and apply this methodology for scale-up of processes in organic synthesis and also in more modern innovative continuous-flow organic electrochemistry. Therefore, this study will provide valuable insight into the effects caused by ultrasound-assisted electrosynthesis and how this technology revolutionizes organic synthesis. It is believed that the hybrid sonoelectrochemical synthesis serves as a solution to the limitations of the commercialization of synthetic processes and offers a new, modern aspect in organic synthesis in a clean, hassle-free, and sustainable approach.
