Article Synopsis
- A real-time monitoring apparatus using UV-visible spectrophotometry was employed to optimize the process of electrochemically-activated persulfate for decolorizing Acid Orange 7.
- The study examined factors like electrode composition, current density, persulfate loading, and stirring speed, and compared the effectiveness of this method with anodic oxidation across nine different dyes.
- It was found that dye structure and functional groups greatly influenced decolorization rates, with azo and xanthene dyes decolorizing faster than triarylmethane dyes, and that electrochemically-activated persulfate generally outperformed anodic oxidation, especially for electron-deficient substrates.
Background: Oxidation is a valuable tool in preparative organic chemistry. Oxoammonium salts and nitroxides have proven valuable as reagents and catalysts in this endeavor.
Objective: The objective of this study is to scale up the oxidative amidation, ester formation, and nitrile formation using nitroxide as an organocatalyst.
A protocol for the oxidation of alcohols to aldehydes and ketones employing an electrochemical aminoxyl-mediated reaction is presented. The approach employs a catalytic amount of the radical and the use of a base is not required. It is performed using readily available electrodes in a commercially available electrochemistry apparatus and does not require a reference electrode.
