Heptavalent Manganese Triggered Oxidation of Menthol and Camphor in Aqueous Sodium Bisulfate and organized Media using Micelles and Polyethylene Glycols

Abstract

Permanganate oxidation of camphor, and menthol were studied in aqueous NaHSO 4 under different conditions. The reactions afforded menthone and camphoric acid respectively. The reactions underwent substantial rate acceleration in aqueous PEG and micellar media containing NaHSO 4. Highly significant rate enhancements are observed in ultrasonically assisted reactions, which were attributed to cavitation effects. Present protocols have depicted several greenery features such as simple work-up, fast reaction times, high product yield, eco-friendly and readily available additives as catalysts.
