Abstract

Potassium iodate was employed as a mediator with concentrated sulfuric acid to electrochemically oxidize substituted secondary alcohols in a biphasic medium with platinum electrodes. Using potassium iodate as a mediator in a biphasic medium, ketones were successfully generated from secondary alcohols. 1-phenyl ethanol is electrochemically oxidized to acetophenone in a biphasic medium. With maximum selectivity and good yields, the several substituted alcohols were successfully converted to ketones. The Platinum electrode had much more electrochemical activity and electrochemical products, according to the HPLC study that followed. The product aromatic ketones were described using UV, FTIR, 1H-NMR, and ¹³C-NMR spectroscopy, and the percentage of product yield was calculated using HPLC. Many secondary alcohols could also be converted to the appropriate ketones at room temperature, with isolated yields ranging from 80 to 95%. During recycling, the product's purity remained intact. It appears that this concept can grow while remaining pollution-free as a result.
